title: Any difference is how much memory is used by REDIS
body: <p>Imagine these two scenarios for REDIS-SERVER:</p>
  
  <p>(A)redis-cli> set "firstname lastname.AT.emailaddress.dot.com" "1"</p>
  
  <p>(B)redis-cli> setbit "firstname lastname.AT.emailaddress.dot.com" 1 1</p>
  
  <p>If 1 million different keys are stored with customer name/email. 
  Use case is that i would like to check if record exists, 
  so 
  in case of (A)</p>
  
  <p>redis-cli> get "firstname lastname.AT.emailaddress.dot.com"</p>
  
  <p>reply from REDIS would be> 1</p>
  
  <p>in case of (B)</p>
  
  <p>redis-cli> getbit "firstname lastname.AT.emailaddress.dot.com" 1</p>
  
  <p>reply from REDIS would be> 1</p>
  
  <p>Question: </p>
  
  <p>Will there be any difference in the amount of memory used by REDIS if all one million key/value pairs are kept in memory for query?</p>
