title: Is there a limit on the number of indexes that can be created on Elastic Search?
body: <p>I'm using AWS-provided Elastic Search.</p>
  
  <p>I have a signup page on my website, and on each signup; a new index for the new user gets created (to be used later by his work-group), which means that the number of indexes is continuously growing, (now it reached around 4~5k).</p>
  
  <p>My question is: is there a performance limit on the number of indexes? is it safe (performance-wise) to keep creating new indexes dynamically with each new user?</p>
