title: Zookeeper Overall data size limit
body: <p>I am new to Zookeeper, trying to understand if it fits for my use case.</p>
  
  <p>I have 10 million hierarchical data, which I want to store in Zookeeper.</p>
  
  <p>10M key-value pair with size of the key and value will be 1KB each.</p>
  
  <p>So the total data size is approximately ~20GB (10M * 2KB) without replication.</p>
  
  <p>I know the zNodes data size limit is 1MB( which can be changed).</p>
  
  <p>Questions:</p>
  
  <ol>
  <li><p>Will zookeeper able to support 20GB of data, with no performance impact.</p></li>
  <li><p>Is there max size after which the performance degrades?</p></li>
  <li>Is there a limit to total number of nodes? </li>
  </ol>
