Happens while we rush something. Yeah. Well, I see your point You don't rush anything because you're not Chris Pratt Hello everyone and welcome to Jurassic World Evolution 2 The Dominion DLC almost forgot what we called it. There's too many Dominion in Dominus Follower King of God knows but thanks to Frontier I've been given the opportunity to record this a little bit ahead of time By that I mean like two days We now have access to not only the campaign which is now 50% done I can barely remember what happened in the campaign if I'm gonna be honest I feel like a whole lot of nothing really establishing the DFW and protecting the dinosaurs But we also have the Chaos Theory, Jurassic World, Dominion, what if scenario. Now the thing is I Apparently this is really hard. It's almost a Jurassic World difficulty So I'm assuming you basically just have to make another park a bit like a Jurassic World was I'm kind of curious about this We're gonna do a campaign first and then we'll do the Chaos Theory We'll probably like today is probably gonna be low There'll be a little bit of campaign probably a little bit of Chaos and a little bit of showcasing the new dinosaurs, of course So let's start off with the Dominion campaign Wait, what was that spoiler warning refers to events from Jurassic World Dominion. Ah, okay I feel like I've basically seen the movie at this point I've just turned off all voices Okay There we go now we can read it We have already sort of seen all this but What I'll do is well, we're kind of need to do it again Basically, I'll try and skip some boring parts. So you're not watching it all again, but you know what I mean? This is the start of part one He did a plan was devised to steal engines dinosaur embryos very slowly An ad placement my god, it was beautiful Yeah, we do everyone knows have you not seen the movie? That's a pox cannon in the universe. They made a movie and everything Decades later business man Simon Mizrani tried again. I won't know if they ever did anything with that can surely, right? Tragically things didn't go as planned That's a bugger waiting for its time and they found it in the aftermath of Jurassic World's downfall Now led by Lewis Dodgson new era was Don't know what the future holds No, we don't Well, hopefully you'll direct the next few dominions or like whatever you're gonna call them Bominion would be new to all these extinction dressable the extinction dresser will part for Hammond's chronicles Because God knows Colin's given up on it. I think Why is he big never achieve once we get another over pink I would I'm wearing pink but like Dodgers really okay a perfectly red We were prepared now we need to finish the job look this bio man. I can't wait. I call way to make a new like Ballerina in here and scape. We are still at a disadvantage until we understand more about this ecosystem and How our new friends will adapt to it? We need more information in time The last thing we want is for them to not adapt and die. Oh, they'll adapt. I believe that They adapted to two parks and a few islands under water grass lovely Just get them here. I'm not sure we are totally ready to understand everything we need to just Get them just shut up I'm really interested to see how this how Lewis Dodgson's portrayed in the movie cuz I'm not Hammond I'm not egotistical proceeds to then be egotistical completely the whole way through so this is gonna be interesting Little bit behind the scenes because I have never recorded anything proper. Well, I've done before I Recorded all dimensions as you can quite clearly see so yeah excuse the blurry side Let's go fix it the next video. I Guess what they say is true. It's location location location more than you realize This is perfect Keeps us away from the public's prying eyes and keeps the political do-gooders at arm's length To think what in gen had and fumbled away They never saw the bigger picture all dinosaur and zero business. That is where the foggy wonky wins We bring a balance that in gen never understood We see the whole picture. Okay. What's our next step? I don't want to waste any time getting this going If you say so is that is this like having to go God? Oh, wow. Oh the hyperloop system Yes, yes, I remember the hyperloop very good. All right. We're gonna try and speedrun just the first few bits Oh, look, there's the mist. It looks so good. I love the fog but it's awesome So good Okay, hopefully the dimensions is all right as well. I haven't tested this This whole new laptop situation with proper games Yes, we need this and then this couldn't can like go In we go Apparently, we need a we need a path he for path best thing they ever did in the game Although we haven't got that I'm not yet so update everything is going to plan We should have the research we need shortly great research. It's the best easiest way to go Also, I feel like I should be lower like I'm like looking like this on my laptop like here I shouldn't really pop it up on someone's laptop, but then I'd block off the fans. Good God I definitely didn't think this through really when I moved here over here. I was like I don't need to record anymore retired Biocin Okay, that did it. We have access to the four facilities research. Look at them go great Oh my god is coming together of each building we get operational Yeah, you just need to ensure we can handle all the dinosaurs when they arrive. I think we can do that Maybe starting to come baby just as we envisioned Yes, please we are leaving engine in our dust nobody cares. I will give them some credit They did resurrect the dinosaurs from extinction. I'm losing money here. I should be a fast-forwarding time on this side We're doing it right Their failures were our education We won't be making the same mistakes Look at the fog. It just all of a sudden comes in. It's so good. It's like the aisle So many people commented that as well Once they did they wanted to showcase them as circus I'm glad I got to showcase that because I don't think anyone else did like the environment Evolution is not just DNA and frogs. It also happens with the fog anyways and advance the world Think of what we will bring to the world. Think of what we will bring to humanity new medicines biotechnology beauty products Yes, curing cancer a new foundation for your skin If you say so Right, there's definitely a couple things I want to talk about as well when it came to this Serenity matter there's one long bit of path. Yes paths working now sweet Just go forward. Yes, where's that there it is There's the stream boom and a boom beautiful, and then we can just put the path to it Go just yeah, I feel like I've seen Dominion at this point. I haven't even Like watch the movie yet. Honestly feel like I have oh also. Yeah, almost forgot to mention this that not only am I Showcasing, you know the Dominion DLC, but I'm also there's a the free updates in here as well I haven't even checked actually what the Free update because I'm brilliant like that me. I'm amazing Me asian pro gamer pro game would be there Right on then and you boom done fast forward. We want to get to show the dinos house Beautiful more dialogue specifically Scientists look over the candidates and let's add some to our operation. You were the first scientist I ever had die Right, so we need is like a couple welfare and yeah, look at that there this Andrew's got it covered look at that There we go. Thank you, Andrew. I have exciting news. We're closing in on some exclusive bios and tech Always say that it'll secure the animals while removing the traditional man-made constructs that have surrounded their environments No visible barrier between us and the dinosaurs Brilliant The more these animals believe they are not in cages the healthier they will be Yeah, that will make them easier to care for I think we'd better place some research outposts as well We can observe our animals safely from there. You know good It's bad enough that dinosaurs never knew what a fence was until we place them around them But what if they become dependent on them to feel safe? Oh? What at least they could see a barrier between us and them How are they even going to trust their environment with invisible fences? How are they even going to know where they are? Oh? Believe me. They'll feel it if they try to cross one. Yeah that Jesus wait. Oh Look it feels like we're messing with them and how comfortable they'll be in their environment Trying to work out what they read it runs the audio is the other one I did and that hasn't stopped us Because they might have oh god here. We go right so we got stegosaurus kalamimus and paracelabra They're not giving this in the seratops anymore sweet Already there we were okay hold much longer And we'll need to research how to get more already done. I'm ahead of you the way forward. Let's get to us Right so I think pretty much we will just do like a big D Through my connections, I've arranged for a number of dinosaurs that connect to our hope it did They're coming all the way from Isla Sorna, so you'll have some time to prepare for their arrival I'm confident. You won't let me down They're going to need enclosures secure enclosures safety is essential for them and us Yes, say that I'm going to get the ground leaf on the go already Brown leaf Let go my stegosaurus Right which way you're facing that it there you go No, go there sword. Yes. You don't need to like hit the certain angles It's it's just kind of fine with with whatever way you want to do it So you need forest you need ground nut and you need ground fire guard your wingy You haven't even explored all your territory yet. There you go. So even more sizable Because stegosaurus missing for it. Well, that's fine. You've got your forest now. Now you need ground fart and ground fiber You are so funny. Oh, I know what I just ground fruit Little bit of food All right, so that's three or three enclosures two more I'm also like let this little bit to be expanded to if we need to walk to it because some things will need paths I'm sure so we'll see what the power is needed. They're okay. Oh They're missing a little bit of ground nut, but I think they're okay Blocking back in there needs friends and You are you're missing a lot of ground nuts. Oh, I'm so sorry So sorry wanting that ground nut, huh? We've got everything happy. Look at that We've got the stegos the galamimus. Oh, well, hold on. Let's see if the stegos actually is happy Yes, it is and the galamimus and I think they're probably the least fuss. Oh, look at that. It's so cool. Oh Yes Leaf apparently never mind. We can make some real progress if we get a really fear connect into our hyperloop Yeah, make sense to me Awesome. Let's make it happen without proper security. We slip into the same chaos That brought down our rivals But our ranger team should be capable of maintaining order. We'll set up the necessary patrols Yeah, I don't have to remind you remote monitoring can only go so far. Of course We'll get right on it. All right. Okay, so we just kind of oh Actually, it kind of works if I put it over here because this is a fence. If I can somehow turn this. Yes The phrase you are victims of your own success are getting because gentlemen, that's where you find yourselves Oh, it's so good. I'm not sure I follow It means we're not job. So we could take on even more Whatever the challenge we're ready then welcome to the bioson genetics research compound phase three This will allow us to continue expanding our genetic engineering division and take our operations to the next level Is coming on you more importantly, I'm counting on you Examples for the best outcome that is something pio sin will write a check for But we're not yet in control We're dependent on others until we get in a position to send out our own expeditions and I don't like being unable to control the outcome of something Golds this research is done. We'll be able to send out our own expeditions We should be in a better place around ourselves. I don't even think I paid attention Played it It's better. I need control and you all right. We need more power. So we're probably need another hydro Okay, hydro plan ready to build an expedition center. Don't forget. We'll need a fossil center, too Understood these buildings will put bios in at the cutting edge of bioengineering Where's the fence? I can't see the fence. Damn it. It's looking quite nice actually Really seem too much of the dinosaurs. I've got to be honest. Look at you Yeah, they're perfectly happy that I thought yeah, definitely to be expanded So we've got a dimetron place we can put in there I don't know what will be able to go with the dimetron on and then we got another place here And then we could probably like expand out this way we can make like a make the path go around sort of thing In fact, that's what I'll do. Oh my god. It's actually really big Do we get a monorail? How do we does it matter? How are we getting money here? Yes? Yes, perfect That should take us to 50% I think Wow, look at it. She's baller. She's completely new as well and she's got like eight for genetics Was that logistics? What's your aid for genetics like right up the bat? So what's really interesting about this is just how obvious it's like whether it's in Jurassic World Dominion or not I'm really not sure because like I said, I haven't seen it yet, but the invisible fences That was just something that the modding community made up It didn't matter whether it's in Dominion or not or if it if it is then I feel like it's it's filtered in somehow from the Community because that's something we've always wanted is invisible fences and yet here we are finally with invisible fences And I if it isn't a movie. It's you guys. It's Jurassic World evolution community. You did it That's it We've had a breakthrough new genome So what you're saying is we've discovered a new dinosaur. I think we've never seen before. Yeah, sort of it is incredible But it's fast incubation. Oh, we'll get to it later. It's a prehistoric synapse and called Dimetrodon. Oh, hold on the trees are casting a terrible shadow. We need to get a good look at this thing when it comes out Hey, yeah, perfect The bios in exclusive. I want five of them A is only part of the puzzle though. We still need to build a hatchery and then synthesize this new breed Once we've done that we can incubate and release them. I'm a pro man They don't call me the game of people of nothing All right five out of six of these Beautiful bug is we're only got four last time. I think Yes, look at them go Gorgeous Oh, look at that. That looks so nice With the red and the light because I only ever released these in the dark. It looks so good Yes, okay, so we need to find out what you guys like I think the promotion Show that Dimetrodon has its eyes glowing in the dark and also Um, I think there was he says something at least in the dlc that I played like the first version of this I finally get it I finally understand why people have a fear of the dark Once you peer into the shadows and see a pair of dimetrodon eyes staring back at you Well, you'll be having nightmares for years Interesting that they they did keep the fallen kingdom Dimetrodon sculpt because it was in one of the exhibits It was in one of the exhibition things in Lockwood Manor where you had a dimetrodon And it looked like this had the same color rings or at least the the sail was orange I think the body was green or blueish or something like that, but they went I'll just make it brown look so much nicer. Well, you're apparently you're drowning I don't even know what you're doing Sorepods compies and package several sorens really the home of paleobiology moving forward Our future is found in the past Sure, we've had some difficulties that was expected, but you handled it well Get this one me now move forward with the next phase of bioson. We have a world-class operation. Let's take it global Bioson will represent the past present and future Come on guys. You want to eat focus on next We focus on upgrading our research compound. That'll give us benefits across the board. Oh, yes These two.  This is beautiful Well, what are we waiting for time to get started on the research? Oh, oh are we are we got oh waiting to get there we go. Oh perfect synchronage there. That was beautiful Yes, that looks awesome. Right. Just wanted a good shot of that. Right. So yeah, we need to do this I know I know But I've got like a research going first because I want to be able to either I think I get more scientists and I also kind of upgrade them. I think What are you blabbering on about now? What do you mean? You can't get to it Wingy wingy whiny team. I want to view my creations Yes, look at them beautiful. Where's my dimension on pep ish? Oh, there we go I did it Look at that. It looks beautiful Everything in gen aspired to be and more It is truly something. I just Just what Well, this is the point in gen thought they had everything in place then it all unraveled from there Yeah, let me put your fears to rest I am not Hammond I am not musrani and his tech first approach. I am all of the above And that is what we're going to do. Oh, no, I didn't mean to imply it then No, no, I understand what you're trying to say that's my tower There is truth in it But we're in a far better position to succeed because others have failed Hammond and musrani both brought tremendous advances to the world. They just had a narrow vision of it We do not We see the whole picture We see the balance of it where there are advancements. There needs to be a business that supports it That makes sense Look bioson's not just interested in the dinosaurs. They have the potential to provide improvements for all life on this planet If we don't jump isn't that how like planet of the ape star The reboot I always felt like maybe they might go that direction Oh, look, we can go inside the place Okay, so I kind of want to check everything else because I I didn't do this when I played the last time If I would say that its name means olympus fire thief A pyro raptor Yes, exactly before we can proceed any further We'll need to send a team out for pyro raptor amber samples No problem It looks like we should be able to achieve a complete Uncompromised genome with the pyro raptor That should make dodson happy. No, don't fire him. He's really good. I need to train him Wait, can I not train him? Oh, I need to do that to train him. Oh, okay. He's already he's already trained But we need look at this prior raptor dread nor does I think that is there isn't a source and kicker I was wondering whether we'll be able to get quets But I assume we won't be able to have quets is not part of biosin So a triceraptor rest there you go is not part of biosin You can rest as well.  I'm so sorry.  That's what you do when you're gonna your job. You never stop working You get taken advantage of like me Look at that. I wish they didn't just dip their head into the water and just drown But hey, it is what it is Oh, they took the thing off for opening the facility and closing it because that was so they've changed a couple of things They've made it so the dinosaurs you put in always get on because that was a bug when the Nozuta seratops and stegosaurus killed each other. They've changed the there was something I got stuck on where it was like How do I get 200? It wasn't a staff. They call it something weird and I was like How do I do that? Right, so now we can go on amber we go to uh, well one of them it should be power after there we go Uh, you and you. Yes, you're very good Um, and have you researched? Yeah, you can rest jennifer. You did an amazing job. Amazing beautiful Uh, so now we need a separate enclosure for power up because they're going to kill the dimetrodons And I kind of want to keep the dimetrodons so we could put the power up is in here And but then I've got all my my facilities taken up. So I what are you? Why can't you get this thing? Why do I need a gate where you could just go over? You did it. Why'd you complain? Right, so we've made one two more enclosures I've made this one specifically for power up there because it's it's quite small Um, and now we just need to get the genome up to a hundred percent to just see how inaccurate and accurate power after is It's uh, it's getting a bit challenging now. Is there anybody with 10? Oh, but that's genetics I want something that's really good with logistics. Okay, I got five of the bat for him. He's 700 000 Why faster expeditions? Is that it decreased? I don't I what he's half price freaking bobby Bobby's MVP. He's super cheap kimberley. Yes cheaper incubations.  You're welcome Oh, yeah, look at that. I got three three things going on. I'm researching additional bays I've got an extraction going on because we need that and I've also got um Oh, I don't even know what the other one is I think with a little research we should be able to get a batch of pyro raptors ready for release All right, then let's get a team on it. It may not be easy, but it is necessary Can you imagine what would have happened already to this facility without us being here? Oh, look, I'd rather Me either so let's stay on task Dude, we gotta do random dinosaurs need us even more the pyro raptors are going to require an enclosure Let's try and make it as suitable as we can for them The last thing we need is for these animals to be irritated. I do have six here if I read like look It's 400,000 or 2.7 million and we only have 7.8 million money. Yes. They're all different colors You know what's on it. Yes, we'll make six of them. Are we ready to see Pyro raptor in loads of different colors? Heck, yeah Oh Oh, oh wow That one looks like um, yeah the middle one this purple one. What's it look like? It looks like something from one of those dinosaur documentaries. I can't remember Oh, they oh, they don't look good. Oh, no Oh this I'm not I much prefer the original Managed to obtain dinosaurs from isla nublar and now I think it's the right time to bring them here We can accommodate them, right? Because I really don't want to let this opportunity pass us by They just did a jump. Oh, that was cool. Oh, there's never does again Okay, so in one minute, we've got ankylosaur, apadasaur and stiggy molot coming I what I need to do is just double over him Let's double check These guys get on what what do you not like mr.  It doesn't say you dislike ankylos. Oh, no, you do you don't you don't like ankylosaur The stiggy molots could actually go with the demort demetrodon Transport the ankylosaur because the ankylosaur actually needs a load of space, which is very scary Um the apadasaur's oh something's got to get on with the apadasaur's, right? Um, do do the pyro raptors get on with the apadasaur's? No Saurapods. Yes, we can put the saurapods in there. So hold on Let me just quickly move all of the pyro raptors into their new enclosure Yep. Yep. Yep. We're putting the apadasaur's in with the demetrodon.  Oh, I would have much preferred the original pyro raptors. I'm not going to lie So demetrodon gets on with saurapods and the stiggy molot as well So I might as well just put these guys all in together then six stiggy molot. Okay. Sure. Let's uh, just put them all in here then Yeah Yeah, these are patasaur's or uh, they're definitely wanting more forest. Good god Right. Hold on a second. Let me just extend this a little bit. Let's have a look at the ankylosaur's Groundleaf groundleaf and forest. Have you explored much? No Sweet nice go explore more before you start being unhappy with things All right patasaur's you'll get there. You'll get there. You're just missing a little bit of forest and really I'm very curious about these stiggy molot and demetrodons because they look like they're the right size to Sort of attacking kill each other. Oh, maybe not. Maybe the uh, the stiggy molot can just sort of like Hit it away. It's a bit too big. I forgot How big is stiggy molot? You saw it with chrisp. Oh god. Yeah pyro. Oh, it's two pyro raptors Oh, okay. That's fine. That's fine. You need more forest Uh, uh, but you have lots of forest though, right?  Okay lots lots of forest.  Well, I hope you're happy with it Uh-oh disease is what I was afraid of There is a disease spreading through our population. This is what happens when you push too far We'd better start researching good cure and do it like yesterday Is it this one? Virgilosis? I feel like I haven't even checked. It's the Virgilosis Well, at least you guys aren't attacking each other. That's good, but I love a check to see what the stiggy molot needs Uh, lots and lots of ground leaf. Okay. Well the thing is because this fence is just so good I really don't need to worry about Um, anything sort of escaping or being unhappy because even if it isn't happy It's not going to run away. Fine. Jesus. I'll aim if you can't even do this They both got it.  Don't even know what this guy's doing.  There you go. They're all healed I think there's still a stiggy molot in here that needs healing now synthesize and incubate a dread notice If there isn't a source and a giga. Oh, yeah, that's simple. Yeah This is the biosin. I'd always envisioned Please report that our biodiversity is solid the facility can support a range of animals That means all of our Bulbias and dinosaurs are in play. We could not be in a better position But Could we not it leads me to think Think about what don't we owe it to the world to bring more to the table? Every new species presents biosin with new possibilities medicine Materials mathematics.  I want them to be a distant memory Right now I want more species as fast as you can make them Don't pepper me with excuses on why not I need ways to make this a reality. Oh, that was cute With all due respect, there is a risk to everything we do The more species we bring back the more complex of a biosphere we have to manage We can only push so far When you think you have pushed as far as you can go push harder This genie is not going back in the bottle. Wait Okay, no idea how long my camera lasted for so, um, yeah So, uh, yeah apologies. I've probably been gone from the start, haven't I? Oh, I need to have 150 operatives in order to go any further because we've dug up as much There is anisaurus DNA as we possibly can so far brilliant. So we're gonna have to do a little bit more research Yes, we're still working. Yes It's come to me going alt tab and saying am I moving? Yes. I do this I go Yeah, yes, I could find a reason to the last of the scientists. Oh my god So what's interesting about this is that I ended up playing or not playing but accidentally seeing The second part of this campaign when I accidentally failed this one I had to restart because I was syncing up the footage that I got from frontier to my footage and noticed That there was a big difference and a big jump between the two And it was just when like I saw that thing and I think instead of frontier Leaving it up to me because they did say don't showcase that not specifically to me but in general Um, so instead of just leaving it up to me to edit that bit out Um, they were like now we'll just cut that So I didn't even get that bit. So I think it's called scorched earth is like the part two of this campaign We were 73 of the way through so that's quite interesting. So we haven't got really that much further to go And we have no money Yay, there we go. Now we do yes We're gonna have to release this by airlift Otherwise, oh no Well, you know what release it regular because we didn't actually get to see it from a great angle last time Uh, and I think we're actually seeing it in the shadow again this time This angle I think is in the the shadowy place Oh, yes Look at it. It's huge and it's about to have a friend Look at you Yeah, let's just actually see it from a normal angle. Shall we so this is The 2022 which should have been 2021 skin for dread notice Ha ha fire Okay, and let's plunk that in too. I think of this enclosure. That's the yeah, there's the other uh dread notice Which is only it's on 87 health. It's thirsty. Are you kidding me? This water in this enclosure. Oh that was fast Oh, sweet. Yeah, we'll do some nozuta saratops as well because I need I just need to get this up. I think there it is faster incubation. So the ho ho Release fire element So I'll put these in with the enkylosaur's because those two get on together saratopsids and enkylosaur's I don't even know what we're on. Hold on. I need to go to research I need the final amber level, but I need 150 Operatives don't exactly know what that means I click on the biosin building The thabi that doesn't say anything sweet We're 131 So I'm hoping they're just releasing more dinosaurs and more species into the park will get me to the 150 You know, there's apparently they want another like shelter. So maybe if I give them a shelter Maybe they'll be happy Oh, there's a parasaur skin of 2022 Oh, there's an is it wait is it a bc? Oh wow Oh, that's cool. Well, let's do a yeah, let's see this one. I didn't even realize, you know, the new A parasaur skin, but there it is.  Yeah, that looks exactly like they do in the movie Is there different calls? It kind of sounds like they have different calls as well. Oh nice Yeah, sweet. Okay, so we got even more right. Let's sedate these guys. Oh, these ones don't have biosin on that's interesting I thought most of the vehicles in this have biosin except for those these helicopters There's probably a way quicker way of transporting the dinosaurs as opposed to airlift because then you do one by one This way they just do them all at once sweet, right? We'll find out whether or not The stegosaurs are happy with them The area's all right. Are they all right? They're they're slowly being dropped in and I don't see any difference So yeah, I think we're all good actually. Oh unless the power is odd No, powers are fine Copentations a little bit of an issue. It's getting there, but not really right. Okay. Let's see this one So we saw the classic. I think that was in the movie. Now. Let's have a look at this one Oh Okay, same model But different coloring As loud as they are. I kind of like it It's a it's a mix like a different model, but it has the lost world sort of patenting on it. Oh, that's quite nice. I like that All right off they go Like a flea circus Yeah, they look really nice. I love the contrast of the white underbelly there Okay, we've done three releases in a short succession of each other and hopefully we can get it the other way Yeah, this is nicer that way. It's very shadowy So this one looks very similar to the last one we just did But it doesn't have the lost world pattern It's got kind of like the drastic dominion pattern. We're only got three so we can't see too many of them But yeah, that one also looks quite nice. Yeah, the pattern on that's pretty cool, too Oh, we got loads over here that aren't viewable. Oh dear. Okay, so If I plonk this in oh, maybe yeah, okay So you can have the link go anywhere But there's only a finite amount of spaces that they can have ah gotcha gotcha gotcha So once we put this up, yeah, there we go. We can research it It was just because half my dinosaurs weren't viewable Just a small little thing. I still think this design's my favorite. I love the blue and the gray Brown it's so nice In comparison to what Jurassic Park 3's power was Don't we like that one as much this is so nice, man. Look at that. It is gorgeous Oh, yeah. Oh, yeah, we can do loads now. Oh, I just increased the capacity. Oh, that's good. Oh, that's good Uh, wait this we all need these so why don't we just put these that genetic specialists So they do it super quick and they cut it in like more than half. Oh Yes, this is probably gonna be a hundred percent there. I'd be surprised if it isn't. Yeah, it's 99% come on man. Really there is anisaurus done Does it have any other skins is the question because there's only one last time It does have different skins But I mean we have to go for that one because the other ones will look if power wraps is anything to go off You we don't want to see the other colors. All right. I finally have enough money to make it Yes, so fast drink abation Uh fast drink abation. Uh, so it's 50 percent quicker basic. Oh So in a minute, we'll get to see the there is anisaurus again This time it won't be killed with my power up.  It just likes everything. Okay. Okay, but would it attack a dreadnoughtus, right? Would it Would it I don't know if it would attack a dreadnoughtus So I'm gonna plop it in there and while I've been doing that I've been getting good DNA Oh, look at it. Oh in fact I've took that out and get those three and heck. Yeah, that's how we do management guys By you. All right, then. Well, let's see how you collapse, huh? Running around with my pointy fingers. It's doing very well. Oh, wow. Whoa Look at that. It didn't look like a broke every bone in its body. So giga is already at 50%. Oh, never mind We could just make it sweet. Oh, anyway, look at there is anisaurus go Beautiful like a bit of a sauropod. Oh, oh, okay. I don't know what's going on with this head. Never mind that But this looks sweet like look at that. Look at the detail on that guy. That's so good.  But what do you need? Coputation very unhappy Uh population fine area fine forest will be fine. It's just the coputation. I think it might be okay, though 1222 Is very dominant though Could be like the brink of it not being happy. It's wait. What do you mean looking for food? What do you need for food? Oh, you need a little bush. Oh, look at it. Oh, it's so cute saying at the second time though So maybe it was supposed to eat it in the water. That's why it was like kind of a swampy biome Looks so cool. Look at this with the fog in the background Like because it's lighter. It just highlights. What's in front is why like in a lot of my thumbnails I'll put light behind things because it really makes things pop and you can see that here. Oh, looks so good Look at you. You're not unhappy. Are you maybe you are everything is fine except the coputation So we'll find out you can't break out though. You're five and these are six Yes, we'll do the one with the least issues. It's got a longevity. That's good Release the giga. Yes for the second time within like three days Oh God lord the light actually looks pretty cool with this guy and for the first time I've released something that's not in shadow Oh, look at that. That's awesome a little bit of slidey there, but we've done it That's now we need to I think we've done all we can Everything you want the choice The choice is ours. Is it second that really We wouldn't be here if it wasn't for you two It would be foolish of me not to include you in what happens next. We don't want any missteps You know, I'd like to see what this facility is really capable of Me too I think it can handle more dinosaurs. Is that right. I know we can I'm proud of you both This is bioson at its best any dinosaurs. We still need in the facility Let me check the research. You gotta make sure we get them all This is too great an opportunity to miss so we need 11 I mean for the dinos and for us With all that's happening. We still want to keep an eye on our dinosaur visibility and comfort ratings Agreed. Let's keep them on target.  Yep. We'll just uh, you know hatch all of those sweet. That's 10 gullies We can just release them into this thing and then it'll be like It's all good next mission Ha ha that takes us over to I think I like how they've just kind of already run out Hey, are we done? We did it mission come wait. So that that's it. We I mean we can probably continue on but That's the first part of the mission done it's It's remarkable Let's call it a bioson sanctuary Although that does sound like marketing rather than reality. Well Reality is the one we make right? Even if it isn't accurate These dinosaurs are an asset to the world. Well, they do share with it However, we do this on our terms and our timelines We've done our best for the dinosaurs and for bioson We did our jobs and we did them well This is no time to be looking back. I did everything and we look forward to all the possibilities that we are about to share with the world to the future of bioson genetics and then just lightning flashes and everything's on fire No, the future of bioson genetics. Oh, so we're going straight We're going straight into the other one. So what I didn't I didn't get headed by lewis dodgson. Okay bioson genetics ushered in a new era of bioengineering Building a utopia for their dinosaur creations But in the shadows Dodgson was devising a more sinister plan. It's the locusts. They were engineering prehistoric locusts Capable of destroying any crop or farmland not using bioson seeds. Oh So Ellie sat learn allen grant discovered their plans and infiltrated bioson's restricted research area They were able to collect the dna evidence. They needed to prove Having the movie ruined before you've even seen it sweet Attempting to cover his traps Dodgson destroyed the evidence causing a catastrophe in the valley He would meet his own demise as a raging inferno tore through the area putting all life at risk Interesting fortunately Most of the dinosaurs were saved and the fire was contained The valley, however Remains a scorched landscape in need of healing With bioson's legacy left hanging in the balance Okay, so this is the scorched earth part of the campaign. Ah Right. Well, there we go. The thing is with dominion, right? It's not a case of knowing the plot It's just you need to see it So I feel like I already know what happens in dominion, but I just want to see it anyway Like I just want to see it unfold in front of me expecting it to be this bad with Dodson out of the picture Hey, it's not I went greedy again such as A permanent viable home for the dinosaurs. It's too busy voicing Mario, man. Can't voice his own character If we do have the experience to take this on There's one thing we don't do. It's easy You can say that again To really get this right. I think we're gonna need some help Funny, you should mention that. Oh I have Just the right people in mind Oh, are we gonna get allen grant and Oh What really gets me the most is seeing these animals injured The buildings bank accounts and egos can be rebuilt but a dinosaur Look at this is a walking miracle of evolution and science You really are a miracle. Is this how I should have done it science and a good determination And sadly a lot of sacrifice too. Oh, this is cool for nothing Where do we start? We triage the situation find the dinosaurs most in need of medical care and treat them first agreed Then we focus on repairing what we can It looks like the fire damage is minimal in some places Sounds good. Let's get started Boopy boop. Hey, look, that's what major climb a ladder What where we going I'm being taken away Let's start by repairing the hydropower hub. Yes, right Energy is the first step towards getting us back up and running Exactly. We sort that out and we get our core buildings operational again Okay, so that's that's the whole reason for this eventually they found the locus And then bioengineered locus that ate Anything that wasn't biosins own crops and it was just all about money in the end Uh, even though I haven't seen the movie kind of a crap plot I'm not gonna lie Feel like uh Kind of came up with something better, right Colin Colin Colin. Were you thinking? What are you doing? That should be a side plot not the whole plot. Jesus. It is what it is So I guess we'll just Escape out of there at speed of time because we can do that because we play God in these games Claire I've just received a report about our transport teams. They're grounded for now by the weather We can't move any dinosaurs captured by the dfw at the moment Well, that's not good. So what do we do? Wait for better weather make more stuff.  Well, you rolled but I get it I was I was consumed by a pyroclastic flow survived You remember dr. Sattler and dr. Grant after all we've been through. Yes. Yes, I do We're all back here again. Hey, how can we help?  I might know one or two hundred We're gonna need anyone specializing in paleontology or paleobiology Or paleobotany. We pretty much know them all You know, it's amazing that a lifetimer studying dinosaurs might just get you noticed, but run from a few and You're kind of a rock star kind of a rock Oh, we got a welfare amazing specialist there. Okay. We need a Logistics amazing specialist there and there we need a Genetics and he's the best that we're gonna do is our war brian to loradan's audio is not as good as sam neils, which is Interesting, so they didn't they mustn't have recorded it at the same location then Is there anything that's really good here a five and a seven? You know what? We'll take that that'll do Wildfire debris a wildfire in biosyn sanctuary has left areas of the valley covered in wildfire debris Dinosaurs cannot be comfortable housed until the wildfire wildfire debris is cleared You scientists declare wildfire. Okay, really? So that the landscape can be regenerated and inhabited by dinosaurs again. Alley. Why are you getting chopped some trees down? I don't know. What are you doing? I would never Never get mixed up in this business again and yet I know but once you see these magnificent creatures You really feel the history of this planet. It's life. It's ecosystem I wouldn't miss that for the world. I know but There's always that underlying need to get ready to run. Well, yes, there is that but Can we just take in the good parts for now? Your life's work is living all around us Yep Still gets my heart beating Look at this outcome. Look at these dinosaurs Don't you wish Ian could be here with us? No Well, we wouldn't let him drive Now we've got some debris So that's why he's he's doing the thing he drove and then tipped the thing over The dinosaurs could reach a lot more usable space uh Okay Cleaning up the sections of storage turf here We'll give them a little breathing on but Won't be easy Sorry grand. I'm I'm a bit Thingy in here Pippa see Don't talk over his audio though There's a good stretch of beautiful land in the valley untouched and perfect for the dinosaurs But to get them there We'll need to move the animals through a lot of fire damaged forest Here's the path that ellie and allen laid out Many of the dinosaurs have the instinct to move in herds in packs We convince a few and the others will follow even the solitary animals Once they see a large migration, they'll be tempted to tag along And the predators will go where their food does they always do Okay, so how about we mobilize our ranger teams to wrangle them through the path? It'll be like a cattle drive but with vehicles and the cows weigh eight tons Haha, this is so weird Okay, it's very um Oh, what you call it? It's very uh jpog because you had this in the helicopter. I think oh do I have to put them through the gate? Ah I get you I get you I was like, but they're not going over the fence man Well, this is an interesting thing to do.  Wow? Okay, there's loads of different things here. Is there a particular way that I'm supposed to send them? I don't even know man Like this way.  So now I can just drive along with them as they go Oh, this is kind of cool actually being able to summon and direct your dinosaur somewhere.  I should be taking care. I should be on Oh, I should be on a parasol at first. Oh and great. You're riding a parasol. Just go Go on What's next for the dinosaurs? Research outposts. Oh, we can construct or repair what we need great. Let's get on it Remember when we first saw the dinosaurs allen when the promise of Jurassic park was so alive Yeah, I was overwhelmed We all were and the potential filled me with hope It was magic it was It truly was but like all magic. It was just an illusion Ah, we're dragging this up. Are we consequences of bringing them back? You might not be able to change the past but We can't learn from it really Like when they failed again with Jurassic world All that technology We do not need those elaborate security devices they had What we do need is more hands-on conservation Range of patrols for instance it could effectively monitor the animals in their welfare, you know Correct vigilance exactly Got to have some vigilance. Okay. Ooh I've unlocked invisible fences not like we had that before but all right Can you get to this one? You should be able to get to that one, right? You can go round Right, so we'll just plunk one in here seeing as we can't actually get to the other things which makes no sense But who cares we've got power So I'm wondering how much more we need to do like we carefully these dinosaurs. Maybe we bring in a couple more Maybe there's some sort of issue With um like disease or something like that, but really there can't be that much can there? I like how they're just running back over the scores. They'll never be happy here. Never be happy. Oh, they're happy Oh god, he's going he's making a beeline for that jeep. Jesus Right. So what do you want? You want tall fiber and tall fruit some stuff that we really can't get But now you can tall fiber now Yes Beautiful. We did it. We made it happy For about 15 seconds Sweet if we're going to see real improvement in the health of the animals We'll need a paleo medical facility. Of course get right on Healthier they are you mean I'll get right on it. What's the problem? It is smoke inhalation. Oh That's uh That's a new one. All right So, how do we how'd you treat that one then? Oh, you need to research it Oh, this was already a thing. I'm pretty sure so with this map I'm wondering if the problem, you know, you have storms in some and you have like Snowstorms and other ones as well This one is like, oh, you might get wildfires. Which is weird because it looks very swampy. So It doesn't really okay. All right. So everything basically had smoke inhalation Except for the dread notice, which I think has got a fracture injured carbon monoxide poisoning So I've already went to sedate it because I'm assuming we'll have to take it to the actual facility to treat that At the car wash now to airlift it back to it home Somewhere there. I don't know That's it. We've done it Clear the wildfire. Well, I would if you had let me So wait I've just been looking over the site if we clear out this burn foliage I believe we can restore the soil to regenerate the plant life we need Okay, oh, she's got zero logistics.  That's so cruel Don't you think that dinosaurs are more exciting than ferns and ivy? Um, I'm in the life-saving business Our future can be found in the soil. I'm smart It's easier to replant mistakes. Well, I don't make mistakes when it comes to plants The other things that's a different story. Do you know how many of these plants are poisonous to the dinosaurs? About half How do the animals know they're poisonous? 65 million years of evolution And here's one just sitting on board Okay, so what do we need to do next time to clear the burn foliage. These are tens. Okay. Okay What about these ones are these? Oh, no, these are being done. Are they so am I gonna need to research like other things? Copy that. Oh my god Should be any minute by now isolate the arrivals Enclosures are in good shape the transport teams are back online. We're ready to go good Because it's about to get busy These animals need us and thanks to our efforts the valley is back Step one, we need to get all the new dinosaurs into the enclosures and step two is to not get eaten in the process Oh, I put them in the wrong way The health of the dinosaurs we need to keep all of the animals from the dfw quarantined away from the others because of we're not careful We run the risk of spreading viral infections. Okay Yeah, like that's never happened before is this big enough for them I'm kind of curious because I might just keep these guys here if this is the case Oh, I like it's drossig world stinger. So it doesn't have a beak Uh, yeah, it's missing a couple of things, but you know what it is. I think if I'm quick enough I could just yeah, I could just like have these guys In their own enclosure over here away from everything because they'll probably be all right I think that's what it's wanting me to do is just like cut this off from the rest of them Oh Are you a special carnitaurus? No, you're not. We don't even have a cool carnitaurus skin. No Right, we'll see what you want open space. What are you? Oh Just a little bit more, right? And you want a lot of forest.  Okay, that was fine. I thought like the open space was meh. I didn't like that But once you Sort of oh, it's probably because of the burnt soil. So it didn't count. It's actually having any land There we go stinger saw completely fine in this enclosure as well So we got to isolate the arrivals from the other dinosaurs. Oops. Oh, they're callous Yeah, I completely forgot about that one. It's a sugar when it's fine. Yeah, definitely. Oh, we don't even have a staff building Ah, that's the problem. I see now. Okay Look at this place. Isn't it neat at the transformation? It's astonishing Makes me remember why I got into all of this in the I'd be here to this moment Idealism, it's not a bad thing Claire. Actually can be a great thing A great motivator. You're right So what's left? We need to treat the injuries and diseases of the animals from the dfw Oh, if I god say that sounds like a job for an idealist What? Oh, well, there we go. We took one Head out for it. Oh, we didn't get anything for it. Yeah, there you are rabies, oh pesky rabies, but you like All I'm gonna go. Yeah, it's all fun. It looks so good I don't know what I can say the fog the kind of very lush greenest that this place is And the tower looks so cool I don't know if I would buy this just for the campaign though I think really where this this whole thing shines is in the different dinosaurs This whole new environment and stuff as well As well as decorations and things there is the free update again. I don't know what that is But it is included in this whole shebangs. I wonder how I even survived all this We all wonder that But let's focus on the facility Now that is rebuilt we need to make sure it can be maintained What if we monitor the status of the dinosaurs we keep them disease-free? And then our work should be done. I wasn't sure we'd ever get this place back under control Think we could call this a success as long as the dinosaurs are comfortable I think so And it's time to test the system make sure it's stable and viable Let's keep our dinosaur comfort and visibility ratings high make that our top priority that and And Not getting eaten Yep, I know I know So I know how are we doing ellie? That's no aslanublar. That's for sure. Well, that's certainly something to be thankful for I just meant the conditions here at bioscenter more challenging the climate The biodiversity the lack of natural barriers.  You can identify and solve problems like nobody else. I have never met Really? Really Flattery doctor grant. No, that's the truth But Sure Well any trace of scorched earth has got to go the remnants of this location's violent past need to be erased for good Then that is precisely what we will do Together Bless the working together to clear this Wildfire stuff away and I've still got another one to do on the other side So But the thing is I've kind of like done everything though So there's there's not really anything else for me to do. Everything's happy We're clearing away select the research compound and close the facility. Oh, wait. What what are we done? Is this it? Is this the end close facility? Park look We did it. Oh, okay Clear it all away done. Nice. So see you later. Bye. At least we got a little video Wow, we did the campaign. Okay Even when they're at their most brutal They're most terrifying The dinosaurs are still beautiful Dodgson misunderstood the true potential of this place Dodgson, he was wrong on so many levels Hopefully this time We've learned from the past And the dinosaurs have as well They know the earth is theirs and that they belong here But it should be ours together Humanity and dinosaurs call me an optimist, but I think we can make it work Yeah, so that when you're being eaten by a t-rex. Yeah, I have a choice And the dinosaurs do too Coexistence you can work, but only if all of us are prepared to embrace it I've got to say oh and It's hard to argue with that It's hard, but I'll argue Wow, okay, that's it. That's the complete campaign done. I think little bugger little bugger I knew but it was gonna do that. Okay. So yeah the end of the campaign with the actual camera working this time I have no idea when that decided to stop. But hey, oh here we are Um, so the campaign it was kind of okay I feel like the first half had more going for it Then the second it kind of introduced Like the herding mechanic, which I guess is now going to be in the game That's probably part of the free features. Um, I think I I really don't know though. I couldn't tell you um But it was okay I mean It it definitely shows that the like the the way the campaign was to start with was dressable with evolution too It should have had that to start with like this game should have released alongside dominion And it really it shouldn't have even been split into two parts dfw and dominion It should just all be one leading up to the events of because they've I mean there's a reason why they're split too Because they really feel like they're just two separate things Um, but it was all right. Uh, it was nice to see some of the cast come back So I've talked a little bit. Um, they didn't obviously get Jeff goblin back because I don't know Maybe it was just a bit busy or they didn't have enough budget probably the latter I think of those two, but anyway, I hope you guys have enjoyed The campaign so far or like the whole campaign. I suppose is that's it done so far It won't be the end of the uh, Jurassic world dominion Um content that we'll end up doing on the game because we've still got all the dinosaurs to see want to do a showcase of that As well as the uh chaos theory, which we'll be jumping in too soon So if you enjoyed it leave a like and until next time. I hope I haven't been Logging in and out too much or my camera disappeared, but hey, oh it is what it is But until next time. I'll see you cuties later. Oh, bye. Bye


So for all of you who are running a Cassandra cluster in production I am hoping from this session that you are going to have a ton of things to think about and to investigate and to take home This the sessions title was popular Cassandra problems I and how to fix them. I lied to you I'm taking you for a ride It's going to be popular Cassandra fixes because the amount of content that I've got it could be a full-day workshop So I'm going to run through it very quickly and I won't have time to talk about how you verify The problems to these fixes exist or how to verify that the fixes have actually worked for you or how to make those fixes optimal so Do not take anything in this session any of the hot list of fixes that I have to give you and Just make changes without doing your homework and your due diligence first I have to repeat that do not take any of my advice in this session and just make those changes So as I said, there's a ton of details and it's because this is basically just a load dump of the health check report That we built up at the last pickle. So we're talking about a Decade two decades worth of Cassandra expertise accumulated and hundreds possibly a thousand of production clusters Analyzed this job is usually three days worth of work per cluster And the report is often up to a hundred pages long So I'm going to try and just skim through it as quickly as I can for you in 30 minutes now In the photo of the last pickles Anthony and Rada van are missing and I would also like to give a special shout-out to Andrew hog and Phil Miceley Who have taken this on this work on in data stacks? And improved it even more Briefly about myself. I've always been involved in open source It's just obvious, isn't it? I hope And What's interesting is like like as a kid if you'd asked me I would have given you Ideology or or reasons of principle and Now and especially looking back at that what I was involved in over time. I can see the pragmatism and You know, it was really always Just about solving the problems that I had at work Faster it was just like I've got a problem. Let's look around for something and rip That was it. So I think pragmatism is is Far more valuable Reason to do open source than we realize Okay, so down to business. I'm gonna break this up into six six six sections And within each of these sections I'm gonna break them down into Three further subsections. I'm gonna talk about the the fixes that come Immediately the fixes that you should be doing in the near term That is like in a three to six month time frame and the fixes that you should be doing a long term now This isn't talking to the severity of those problems. This is a trade-off between the severity and the cost of change the risk involved and You know the the cost of verifying both the problem and and the changes So first up infrastructure the infrastructure has a base slide to it These are just that some of the base recommendations that you should That you should be aware of Cassandra nodes Only really only work in a certain range of specs. So we say from 8 to 16 cores and 32 to 64 gigs RAM is good for about production node If you have nodes, which are over 20 cores or over 120 gig of RAM You're really not going to utilize those machines And so the recommendation there is to to either use containers use Kubernetes Kate Sandra project for example or from for zero onwards You can actually because all the ports can be configured run multiple nodes per port This may change especially as we see, you know with what tries is happening and tries is doing with the memtables and If they become properly off heap This may change over time. So pay attention to it. The other one is use separate dedicated discs for each node Discs are usually in the category of about two to eight terabytes that's because you don't want to fill them up more than 50% and the the popular the size tid and the level of compassion strategies They don't really want to work over four terabyte. We have seen time window compassion strategy tables kind of go up to 16 terabytes And nodes work. It will still make your arrange movements or streaming incredibly painful So that is a recommendation again with five zero with unified compassion strategy and with the tries memtable and SS table This is going to change. We're going to see the ability to store a lot more data per node Okay, and and don't use sand Don't use sand because an angel dies every time someone has to tell a Cassandra user don't use sand I'm not going to explain it Simple benchmark to to run if you have info people who are trying to force a sand disk on to you or something is run 10,000 IOPS Soak test on each node at the same time That is your baseline if you can't do that if the controller starts to jam up The production class is not gonna work very well Okay jumping into the immediate concerns Okay, I have hiding in place for upgrading always the latest childcare patch and the latest Cassandra version You know, it's such an obvious advice, but we just jump into so many clusters and they're just behind This should just be automatic for you user kyber IO scheduler The knob is also quite popular for a lot of people It's hard to give an absolute definite advice everyone on this one, but we have seen kyber again and again Just be the right choice disable swab a Lot of people just kind of like we always say, you know Swab off and VM swapping this tool tool tool one not zero because there was a kernel bug at one time Where zero would cause problems and we say it's really important to do both people say like why? one's enough and the problem is that kernel upgrades and other things can happen at the infrastructure side often by different teams and a Swap setting can accidentally accidentally be undone And that can have a cluster-wide impact and bring cluster down. So it's a line of defense Otherwise the that the Cassandra three prod settings recommendations on the data sex website is really good I hope we can upstream them That's a pretty good baseline Yeah, I was gonna keep moving Okay, so critical items here Like the new term items Have an NTP client running on every node and every client application server More than that it has to be part of your monitoring and you have to have alerts set up for clock drift Trying to debug problems related to clock drift in a Cassandra cluster. All right, absolutely Also pay attention to found repair logs and B99 latency changes a long-term infrastructure Things to do if you are using multiple data directories in Cassandra stop Replace that with LVMs There are so many bugs and limitations around multi data directories setups in Cassandra Just don't do it. Also major Cassandra upgrades are more involved than people think they require a lot of planning And a number of careful sequential steps to do properly There is a great documentation on this on the data stacks website Which we are again hoping to upstream to the Cassandra website Quick note on the the the EOLs the Cassandra community has recently agreed that it will only maintain the last three Branches so that it effectively puts an EOL on That fourth branch People panic about this But you know hate to tell you open source doesn't give you support You know if you're that worried about EOL branches, maybe you should go to a vendor and sign up for support What we mean is we simply recognize the number of contributors and the number of committers that we've gotten the project We really can't man more than three branches. So that is what we're committed to so we're not going to see bug fixes From that group of people on older branches CVE's Maybe it depends again. You may be asking us to work on weekends and we'll make that decision Of course Vendors they can come in and they can say we would like to support older branches and and if they bring in contributors who putting bringing Fixes that will change Okay, so moving on to configuration Consistent config on all nodes. I guess so many of the things I'm gonna list here are just so obvious But the number of clusters that we've seen and every M of ours different It's it's horrifying and that's why there's Monk scream there because these are things that I I'm embarrassed to be up here talking about Logging it's not a big deal, but the logging is by default configured with Logging to places to file and to stand it out and very few of you will need both places And typically not the standouts turn it off garbage collection Just use G1 Even on the newer JDK's We see benchmarks where ZGC or Shenandoah on certain use cases perform better Sure But what we're seeing is that G1 is actually really good It's up there and it's just easier to use and it's what you should have any way your best setting for heap is about 2024 gig do not go over 31 and For the best G1 settings look at the trunk or 5-0 JVM options file Also, make sure to set the floor the new size of the heap Set it to about one-third or to half the G1 is supposed to with the ergonomics Adjust it just never gets there with the new heap. So you got to give it this hint to get to the right place quickly The other one off-heap and tables this gives you a 10% right throughput increase is the one to test There are some cases where it won't work for you though the two main bugs that I know that people Hit that prevented them from using off-heap have been addressed So I think that advice comes in even stronger Moving on So near-term configuration changes You should have for each DC three seeds listed and Each node should list those three seeds from every DC consistently The failure policies that you have in the YAML Never do best effort.  Detect and flag a node that is down that is in that stop zombie mode Or do you have a system that's going to automatically restart Cassandra if you do kill it? So depending on how your system is set up you've got to choose these ones correctly Once your cluster is operating well, and you've got decent hardware Jump into the Cassandra YAML and add this dynamic snitch disabled It gets in the way on well-performing on well-performing clusters and since Cassandra 4.1 We have guard rails each heart out on them. They are a lifesaver for operators There's heaps of them and they just keep on getting added to From everybody because everyone is seeing an immense amount of value on them long-term changes Keep an eye out for ring in balance That can cause problems over time and it's a little bit of a hard one to fix in Large clusters or over capacity clusters There's a new setting allocate tokens for local replication factor since 4.0 Take advantage of it and when you use that don't worry about small imbalances that you see Because the point of that allocation algorithm is to account for Future nodes and so it kind of is always a little bit off But it makes sure that each step stays within a certain error Margin also we are currently working on a Cassandra latest YAML file that should land I think in the next week or two That is really for new clusters the the set of options that you should be using We can't put that into the Cassandra YAML file because the Cassandra YAML file has to look after people who are upgrading So it's got all the conservative defaults keeping in mind people who are upgrading the Cassandra YAML is what we'll be pointing Anyone who wants to do benchmarking or to kind of replay with Cassandra to Okay, so moving on to data model This is a big one the two big issues in data modeling would be tombstones and Wide large or hot petitions You know I'm not going to go into them, but but kind of number the issues will kind of touch on them so the hot the hot or the critical list is Remove unused tables Tables have a memory overhead in Cassandra Cassandra is not a good place to park data So if you have tables if you just like taken kind of like copies or something and there was no longer any Reads happening on those tables get them out of your cluster Disable both the local and the DC local read repair chance This reduces five to twenty percent load on your cluster and that this this Async read repair chance it offers no operational guarantees So there's a really there's nothing that you can work with in a concrete way And it adds a significant amount of load to the cluster in the recent patch versions of all of our branches It has been removed compression chunk length Bring it down to 16k if you've got skinny rows even bring it down to 4k And then once you've done that upgrade SS tables So that the compression kicks in it's only going to work if you've also Put your disk read ahead to 4k that was really important one I skipped over it They go hand-in-hand Make sure your dev teams or your applications are syncing their schema changes As an operator dealing with schema disagreements can quickly turn into a huge nightmare Yes, it's kind of supposed to be able to do concurrent schema changes, but in practice you're living on the edge Get the dev teams to sync their schema changes This changes in 5.1 with transactional cluster metadata where you will be able to do unlimited concurrent schema changes Disable a rocache really never works especially over time people set it up They kind of tune it that works six months later. You later just start There are better ways to do that also check your prepared statements in the clients again and again and again We see string literal sneak into those prepared statements and that thrashes the Prepared statement case on the server It's something to keep an eye out and there's no way to hide and force it enforce it near term It's a long slide. I know Don't do secondary indexes before SAI I'm favored in normalization Don't try to avoid unfrozen collections and UDTs The performance difference between and the problems that you encounter between frozen and unfrozen is significant So whenever you're using UDTs or collections, if you can freeze them Just do it. If you are using unfrozen lists Try to use a map or a list or add a clustering key instead the list collection time Unfrozen is not good. Don't use materialized views ever Sorry I'm not gonna go into that one The whole section here on compaction strategies, I'm not really gonna go into that because with 5.0 We've got unified compaction strategy And you really just like just upgrade and just start using that Again Unlogged batches They're only for a single petition people think that they're wonderful performance gain. They're not Cassandra likes Concurrent in like small concurrent requests This idea of kind of trying to batch up a riot even within a single petition. It does not work Maybe like between 10 and 50 rows max in an unlogged petition may give you a small benefit Don't go beyond that logged batches They're fairly much don't give you any guarantee They trip people up There's a little bit more dev work in complexity To just do it manually by ordering the rights and then ordering the reads in the opposite way With the retry logic in place that's usually a much better solution again Cassandra 5.1 with a cord Fixes that problem for you Gc grace seconds is an interesting one. We see again and again People play with GC grace seconds try and fix their tombstone problems. It is not the first thing for you to play with It's nearly always done wrong GC grace seconds has a number of constraints Or interact or odd interactions with it First of all, you've got to be running repairs within your GC grace seconds That's the easy one, but it also plays with the max hits window and the TTL and it you get some odd behavior If you GC grace seconds check it goes blow above those but blow some of those values We have an excellent blog post on the last pickle website that goes into that in more detail Also configure your speculative retry both server side and client side to hard-coded millisecond values Usually something between the piece 75 and the P90 Latencies doing normal operations Is a decent starting place for you to think about it really depends on how much you're willing to sacrifice load overhead for a bit better performance But when you do that Also at some point go and test that the cluster can still run when speculative retry is at all Otherwise you have a cascading failure problem Long-term issues don't overuse lightweight transactions Like weight transactions. They do heat contentions. They do time out If you have a lot of lightweight transactions, I recommend you to upgrade to 4.1 and When you upgrade to 4.1, it does not automatically use the second version of Paxus So the second version of Paxus that came in 4.1 It halved the number of network trips. So you're going from four network trips down to two network trips That's a huge improvement on your cluster. But the problem is It doesn't automatically use it. There are some manual commands and as far as I know, they're not documented anywhere So good luck with that Now reach out and ask Don't do more than a thousand tables and Designed for collections less than a thousand. Yeah, the limit is 64k But what we see is that at design time, you're gonna have going already over a thousand then in production in a year You're going to be in pain So at design time, you think those collections are gonna need thousands of entries Try to find a different solution for that Okay, jumping into operations If you're not familiar with the UDA loop from the US Air Force, please read up on it The basic idea is that you take these sequential steps before you take any action You sit down and you collect observations in an unbiased manner You get as much observations as you can Then you start to orientate then you allow your biases to come into the picture Then you build hypothesis and you weigh multiple Hypotheses and you weigh them up against each other and then you make a decision at any of these steps You eagerly go back to collect more observations. Once you're confident you make that change and you verify the change and If it was no good you undo and start again Your monitoring systems your logging systems your tracing systems your backups all of those emergency ops They have to work when your platform is on fire These infrastructure tools need better availability and redundancy In many situations then the production system itself You know because of the production when the production system is on fire. You are dependent upon them To see what the problem is so it does not happen again. So operations Neat home Okay, keep an eye on wide large hot petitions It was interesting and a number of other another session at this summit who are saying 10 megs. I go with that The hard limits really for a wide petition before 311 was 100 meg Say softly that would be 10 meg that was accurate From 311 upwards We can actually handle wide petitions a bit better Last the high limit then moves up to about a gig This is not talking about large petitions large column of data cells And it's not talking about our petitions long list here Anything I'm super interested in talking about Okay, so two items here. What's your per table compression ratios? One of the things that we see in all of our reports is that there is maybe 10 percent Of the tables are not getting any benefit whatsoever from compression You know it's super simple just jump in just turn compression off on those tables Otherwise, you know this this You know half of the the remaining tables Simple adjustments Could save 10 percent Discusage for you. I know like I was we were speaking about this the other day and You know like the engineers in the room immediately jumped on us like yes Yes And we should come up with this new compression algorithm and we could you know have a custom dictionary based on the data You've already got and they have even better compression ratios and for me That was a little bit like when you talk about climate change and people talk about brand new technology They want to invent and like just stop it all the solutions around Just get to it and fix it low-hanging fruit But people don't do it because it it's quite cumbersome and takes a bit of time The other one was watch out for anti-compactions Again and again and again. We see clusters thrashing around with anti-compactions And we say you're doing incremental repairs and they're like no Wow like like repo or your schedule repairs are not got incremental repairs anywhere And what happened was some operator at some point run one incremental repair and that put Repair that timestamps on the ss tables and from that moment onwards you had anti-compactions running in the background You're basically doubling your Repair load and it's a bit cumbersome to the go through you got to kind of turn off the node and Unset all of those repaired at timestamps and turn it back on to get out of that situation a long-term things to check out for You know test your hint window and your the replay speed of it It's one of those things that People don't find out until they've had a node down for an hour or two They can't actually get that node up and running again, and it's because the hint replay is working too fast You've just got too much in your hints So take the time when you can to figure out What's the correct? Throttling rate for hint replays, especially when you have like an hour or two worth of hints. Okay, so security only once Slide no couple of slides for security Low hanging fruit in the Cassandra Yammel There's a number of kind of like interval in milliseconds or validation period in milliseconds. I think there's six of them There may be nine of them now I can't remember they're all set to quite low values increase them all up to 30 seconds You know having like if there's a problem there or like there's checking your your Your your off tables and roles tables too often that can cause problems The other one is the system off key space Increase its replication up to the number of nodes you've got or just like a higher number like five or even more and use NTS so you make sure you've got copies of it in each type of center and Yeah, do I have to say it?  Okay long term There is so much to go through here. This is in basic basic highlights The problem with security is there are no half measures You really need to do everything here properly carefully Just go read Nate McColl's blog post last pickle He goes through all the steps Well on the last pickle is also some additional blog posts, you know around Requireings the client Authentication, which is really important. It's a must and if you're using a common CA you should also do Host name verification Okay, last slide of the deck It's called trouble shooting, but you know, I probably could have called it verification Because when I say, you know, verify the problem and verify the fix the method is pretty similar to troubleshooting um So one thing one of my favorite things to tell people is Be familiar with the P 95 to P 99 spread derivative and what I mean by that and this is applies to both read and write latencies is That you look at the gap between your P 95 and your P 99 latencies and how that changes of your daily traffic shape And how much it pulls apart in peak traffic and then look at that? over three six 12 months That's going to give you some interesting insights as to the saturation of your cluster and and saturation growing over time as well as Potential hardware problems and other kind of like non Cassandra problems that may pop it pop in If you have any problems with CPU with CPU Increasing CPU getting saturated Take a flame graph before you do anything like even if you're 100% confident with the problem is please for love of God Just take a flame graph Flame graphs are also a fantastic way of getting into the code of Cassandra. It's it's not the best code base To begin learning with and to sit down and to try and just start reading it from scratch is pretty painful But the flame graphs are actually a really fun way to get into the code base Also be familiar async profiler to the fame graphs These tools D stat I have top if you've got a newer version start learning the PCC tools and for your GC Profiling even though G1 is pretty good if using those latest GVM settings You probably don't have to but if you want to do GC tuning just go and use the GC easy website It's fantastic, and it's free That's me Thank you very much and a quick plug to because community overcode happening in Europe Next June if you're from Europe. Are you close by? Please come and join us there Thank you Questions I will load them up. Yep. Thank you for reminding me question Polo again a thousand But yeah, I didn't put that in there's there's a number of things that could The list is long. So again, it was the popular problems The high column count we don't see it that often now and again Yes. Yes, we recommend them Absolutely Nearly all of the time it would do it's it's much much lighter than running for repairs caveats with incremental incremental repairs is that a lot of clusters you will still need to do token like break it up into smaller Repairs because not every incremental repair is necessarily Small if you've like loading if you're a table where you're coming to full asset loads like once a night Then you're that incremental repair is still a full repair, and you'll have to tune it the way you did before Also, you still need to Do full repairs Every couple of months maybe like for the sake of disc rot you've got SSDs It's still helpful to do those four repairs sometimes your question was on timeout values The valid reason for increasing timeout values is for example with if you have analytics DC Or Your client is not low latency like if you have an application which is more throughput based Then you're you're you're gonna throttle the configure you're going to tune throttle the configuration based on throughput not on SLAs or SLOs So that's why people increase the timeout values. We have no way like we have no way of Quality of service so you like like if you have to have like ad hoc queries on your cluster, and you know that they run Forever and so then you have to kind of increase that timeout and that sucks because 99% of your traffic is actually low latency traffic Where you would like to have a like a low we don't have a solution for that yet. It's been discussed a number of times I know people talk about this One way to solve that is if you have separate DCs So you have a DC which is analytics, and then you do it all ad hoc on all that stuff on there You can figure that differently, but Have a good use case for that and you like to write it up and submit it Like do that to the community because we need to hear more concrete use cases where we say yeah, that's legit And we'll start to form kind of more ideas on on ways to to solve that


If you've ever been in a bad work situation, or a bad work environment, being in a good one can make you appreciate it even more. Because in a bad work environment, you got coworkers who just, they don't ride for each other, they don't help each other out. You may have a manager that really just doesn't really care much about you and may tell you that they want to get the best out of you, but they don't really put forth that effort. And they don't invest time into making an attempt to really get the best out of you. But with the Ravens, it seems as if that is the exact opposite. Raven seemed to have such a good work environment, such a good vibe throughout the team, just such a good energy. They obviously had a lot of fun throughout the season. They joke around with each other. They have fun on the field, off the field, and it shows. It shows. It showed in the game play. It showed just when you see them via social media. You see them in interviews, post game, pregame, all that stuff. And it's been showing through this offseason two, just the support that they have continued to have for one another. Now there can be jealousy in the work environment. There can be envy in the work environment, especially when you see one of your co-workers come up, because you may feel, some people may feel, oh, your coworker, he doesn't deserve it. He or she doesn't deserve it. I've been putting in work for as long as them, or even longer than them, but they got to come up before me. What's that about? But with the Ravens, you saw somebody like a Matthew Judon, when he got franchise tagged, you saw nothing but congratulations. You saw nothing but, hey, I'm happy for you, homie. And you saw just a celebration with all his co-workers. And now with Ronnie Stanley, his co-workers, they're coming to his aid when it comes to him being paid. So there was a tweet from Pro Football Focus about the Ravens, about Ronnie Stanley in particular. And it said the highest pass blocking grade in 2019 went to none other than Ronnie Stanley. No sacks allowed in 2019, regular season went to none other than Ronnie Stanley. And it said that Ronnie Stanley is becoming a premier left tackle. So Ronnie Stanley has shown that he is consistent. Ronnie Stanley has shown that he is one of the better left tackles in the league. Ronnie Stanley has shown one of the biggest things when it comes to being a professional football player that is so important, and it often goes overlooked. But when it's a problem, oh, you know it's a problem, and that's being healthy. He's been there, he shows up all the time, and he does his thing. So that led to Willie Snead. He caught wind of that. And he quote tweeted and said, pay that man, pay that man, pay Ronnie Stanley. And this has been something that we've discussed on here quite often, especially recently since Ronnie Stanley, he's in the last year of his contract. He could get a contract any day now, any day now. He does not have any restrictions right now for when he can agree to terms with the Ravens. They could announce any day now that, oh, we've extended Ronnie Stanley. Oh, we came up with a contract agreement with Ronnie Stanley, any second. But with Ronnie Stanley, it's just, it's not that simple. I wish it was, but it's really not. But Lamar chimed in too, and he said, please, please, and put three of these emojis, even though these are really high five emojis. A lot of people think that they're like praying emojis or begging emojis or whatever. These are really high fives. But anyway, he put, please, and you can understand why both of them, and I'm sure plenty of other people on the Ravens would be advocates for one Ronnie Stanley getting paid.  No sacks allowed in 2009, like none, zero. Now Lamar Jackson is his quarterback, so that certainly plays a part in that because if somebody were to get past Ronnie Stanley, then enough times Lamar could evade them. But still Lamar didn't evade everybody last year when it came to being sacked. So for Ronnie Stanley to really hold it down like that, for him to really, literally hold up his end of the bargain like that, that's a beautiful thing because your quarterback, you're protecting his blind side since he's right handed. He can only see, well he can't really see what's behind him. So you being that left tackle, you're protecting everything on his left side because as a right handed quarterback, you're like this and the left tackle's over there.  You got to have pocket awareness and pocket presence, but to have a good left tackle that's holding it down like that, that's a beautiful thing. That certainly isn't something that is underappreciated by Lamar Jackson, like he stated, please, in support of Willie Snead saying they need to pay Ronnie Stanley. Now, with the Ravens paying to Ronnie Stanley, again, I am not envious of Eric DeCosta. And now with all the possibilities of next season, Eric DeCosta's job just got that much harder because as you know, the NFL and the NFLPA, they came to an agreement on how this league year is going to play out. They came to an agreement with the testing. They came to an agreement with the salary cap, but with the salary cap, some of the specifics about that is that this year is going to remain the same because there were some talks about potentially dropping it this year. And if they dropped it this year, ooh, that could cause a lot of chaos because a lot of teams are close to the salary cap. They're right up against the salary cap like Ravens right now. They only have 7 million cap space. And with them only having 7 million cap space, if the salary cap were to drop, if it dropped 10 million, then okay, you're 3 million over, you got to cut somebody. If it were to drop 25 million, oh man, then stuff just gets scary and ugly, but they don't have to worry about that this year. But next season, they're saying that if the NFL suffers enough losses, enough revenue losses, then the salary cap is going to drop to 175 million because again, right now it's at 198.2 million. So it would drop to 175 million and they would sort of try to cover the losses over the next four years from I think like 2021 to 2024, something along those lines. But the salary cap will be lower. So a lot of teams that like that's going to make stuff that much harder. But speaking for area to cost us specifically, now if that's the case, it's so much unknown with that. And that can make it very, very scary. Because you don't know if or when or by how much the NFL, how much revenue they might possibly lose this year. But if they do, then you'll know, okay, well, salary cap is dropping, salary cap is dropping next year. So now that really has a huge impact on your future deals, guys who you would normally come to an agreement with. And this is not just obviously with the Ravens, this is league wide. So a lot of tough decisions are going to have to be made. And it's a possibility too that some guys may have to end up taking a little bit less. They may really have like, you may not have any choice. There's going to be like, I mean, we already see a lot of crazy cuts every single year. We see a lot of crazy trades every single year. Next year, if the salary cap drops to 175 mil, you will see that even more. Because salaries are going to have to get cut, rosters are going to have to get reduced.  But if the salary cap drops by that much, you really can't pay everybody. You really can't. And I mean, it just, it's just a tricky situation for the Ravens specifically, but again, for everybody. Now Ravens as of right now, according to the spot track, as of right now, if the Ravens left everybody on the contracts that they're currently on right now at this moment, then next year, they would have with the salary cap going down to 175 mil, they would have about 30 million cap space. And while some people might be, oh, that's not too bad. And it's not, but Ronnie Stanley, free agent, Matt Judon, free agent, Marlon Humphrey, eligible. So I think they will put that on hold. If the salary cap did does drop Lamar Jackson, eligible, I think they will put that on hold or depend, now if the Ravens win the Super Bowl now, that's, oh, that's pressure right there. I don't really think Lamar will sweat it and I think he'll be willing to wait. But at the same time, it's like, hey, I just want you to Super Bowl. We just won like, hey, what's up? So, so much stuff just depends on so many different situations. But again, no, I'm not jealous of Eric DeCosta. And then, of course, there's Bowser, there's Jihad Ward, there's L.J. Fort, there's Jimmy Smith, there's, it's plenty more to is Derek Wolf.  So that makes those decisions just that much harder. Well, at the same time, it could make it that much easier.  And everything, of course, depends on their play throughout this season.  Should we extend them? But now with the salary cap, it's going down. It's like, oh, maybe not. So hopefully for NFL, say they they still end up making a significant amount of money. I mean, you know that they still going to make plenty of money, regardless of especially since everybody's going to be watching on TV now. And if there are fans at the stands, we'll see what happens. But if there aren't any fans at the stands, then the TV ratings are going to go way up. They're going to go way up since everybody's going to be at home watching. So they're going to make a significant amount of money. But at the same time, they are still going to lose a significant amount of money because it ain't nothing like ticket sales. Ain't nothing like being at the game, fans buying food, memorabilia, paying for parking, like that stuff adds up. Like, when you think about that, like 71,000 people going to a game and not every stadium holds 70,000. Just just even use 50,000 just to use it as an example. 50,000 people going to a game. A lot of them are going to buy food. A lot of them are going to buy drinks, buy beer. A lot of them are going to buy a paraphernalia, jerseys, hats, gloves, whatever. Some people may be visiting. So they they like, oh, you know, I got to buy a lot of stuff. This official team stuff straight from the official store of whatever team you're going to. I got to take it back home on my way back. Let me get all this. And then, of course, like we said, the parking, they got to pay for that. And it's just it's so much money that goes into actually going into going to the games. Again, it is a beautiful experience. It's a fun experience, especially when your team wins.  But to NFL, NFL is definitely going to suffer. They're going to take a loss. But hopefully it's not enough to where that salary cap has to get reduced to 175 mil, but it's going to be it's going to be tough. So it's most likely looking like that's what's going to go down. But we just got to wait and see. But as far as Ronnie Stanley, this affects him a lot. And like I said, it affects everybody a lot. But I wonder if this has changed the Ravens dealings with Ronnie Stanley. I wonder if this has, I wonder if they were may have been in deep talks with him. And maybe they were progressing inch and closer and closer to a deal. They're like, OK, we're getting there. We're getting there.  OK, you know what? Let's let's put this on pause for now. Let's just wait. Because we don't know what's going to happen next. But then even with that, since he's in the last year of his deal, what if they don't come to an agreement with him all year long? Now, I don't. Well, I do see some scenarios where they actually let him go or they trade him or something like that. But I don't think they're going to do that. Anything is still possible, of course, but I don't think they're going to do that. But if something happened and there was no deal. My sense is going to be a free agent next year. Now, there's no way I see the Ravens just letting him walk completely free, free agent. I think the worst case scenario for the Ravens to do with Ronnie Stanley will be if they franchise tag them and then they traded him for like a first to first or first in the second or first in the third or whatever. And because they're going to be teams that have more money than the Ravens. That can accommodate Ronnie Stanley better than the Ravens can. And Ronnie Stanley, he's going to want a record breaking contract. He is going to want a record breaking contract. And if you've been performing at a high level, then and you see what Larry Meetons would just got. It's like, am I not better than him? Yeah, let's do better than that. Let's go. And then Lamar Jackson, when he gets paid, he's going to want a record breaking contract. But I think that with him, like I said, I think it'll be something that that'll do well for both him and the team. But then you so you got Lamar and again, you got Marlon Humphrey coming up too. One of the better cornerbacks in the league. He's going to want to get paid. You already paying Marcus Peters. You're paying Earl Thomas. You're paying Tavon Young. You like you got a lot of money in a second. So again, this thing is stressful just thinking about it. And I ain't even know GM. I ain't paying nobody. So shout out to the Costa. Much love to you. Need to drink some Kava tea. Was it Java tea or Kava tea? I think it's Kava tea. But it's some tea that just relax yourself. Relax, stress free tea, relax your muscles and all that. I'm sure the guys have got plenty of that. But anyway, team keep it clean. I appreciate y'all. I love you all. I hope you're having a great day. I appreciate you for listening. I appreciate you for watching. And y'all just keep being great. Keep being you. Keep just just tell somebody. Like I said, tell somebody you love them. Tell somebody you appreciate them today because you you never, never, never, never know just how you could brighten up. Not only somebody's day, but somebody's life. By just letting them know something that simple as that, that you appreciate them. Anyway, I appreciate y'all. I love y'all and I thank you. We out.
