title: Get all keys in Redis cluster
body: <p>I am using Redis cluster version <code>redis-5.0.5</code>. I want to see all the keys present in my Redis cluster. I know for standalone we use <code>KEYS *</code> to get all the keys. </p>
  
  <p>what is the way to see all keys in Redis cluster?</p>
  
  <pre><code>$ redis-cli -h hostname -p 90001 -c 
  hostname:90001&gt; KEYS *
  (empty list or set)
  
  // I have data on my cluster 
  </code></pre>
