title: Redis vs elastic search in my use case
body: <p>I am about to create a project that monitors our cache usage.<br>
  What I mean ?<br>
  After each cache operation (Add/Get/Remove), I will save data e.g Class name, size of object (or byte[]), duration operation took and other fields that i may need.<br>
  Then i want to enable querying, or use a tool like kibana to visualize the data, to show in graphs how many instances i put of each class type, what is the average Add/Get time, if some instances of same class took longer to add to cache - I want to know and maybe investigate these objects.  </p>
  
  <p>I am wondering if i should use Elasticsearch to store the data or maybe redis/mongoDB. And what about visualize tools.<br>
  <strong>What should be considered</strong>   </p>
  
  <ol>
  <li>IO - read/write should be fast</li>
  <li>Deployment - fast and comfortable</li>
  </ol>
