Instagram like Social networking using mongodb and node js
<p>I am using mongodb with node js in my application. We have users collection and events collection. </p>

<pre><code>Users :-  "user":{
"name":[name],
"email":[email]

}

Events :-  "event":{
"title":[title],
"venue":[venue]

}
</code></pre>

<p>Previously users can only follow events but cannot follow each other now i am also making social networking around users also, so users can follow each other and their feed will get changed accordingly exactly like Instagram. </p>

<p>so my question is as my main database is Mongodb, so should i make this social networking using Mongodb only or should i use some Graph db and put all my user data from Mongo db to Graph db and maintain both the databases simultaneously   </p>
