How to use redis for number of micro-services?
<p>I am very much new to redis. I have been investigating on redis for past few days.I read the documentation on cache management(lru cache), commands ,etc. I want to know how to implement caching for multiple microservice(s) data .
I have few questions:</p>

<ol>
<li>Can all microservices data(cached) be kept under a single instance of redis
    server?</li>
<li><p>Should every microservice have its own cache database in redis?</p></li>
<li><p>How to refresh cache data without setting EXPIRE? Since it would consume more memory.</p></li>
</ol>

<p>Some more information on best practices on redis with microservices will be helpful.</p>
