title: Cassandra Java driver Performance : CQL Queries with IN Clause having high no of values
body: <p>We are using Datastax Cassandra java driver (version 3.x). There is a logged batch Select statement with 'IN' clause, having a high number of values. Due to which we are facing a serious issue of low performance. Following is the format of query visible while debugging the Java application:</p>
  
  <p>SELECT COL1, COL2, ... FROM XXXX WHERE PARTITIONKEY IN () AND CLUSTERINGKEY IN();</p>
  
  <p>Can anyone please share how such SELECT with more than one IN clause shall be handled when there is high number of values available to pass inside it.</p>
  
  <p>Does Session#executeAsync can solve this issue. </p>
  
  <p>Thanks.</p>
