[jira] [Created] (CASSANDRA-7928) Digest queries do not require alder32 checks

sankalp kohli created CASSANDRA-7928:
----------------------------------------

             Summary: Digest queries do not require alder32 checks
                 Key: CASSANDRA-7928
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7928
             Project: Cassandra
          Issue Type: Improvement
            Reporter: sankalp kohli
            Priority: Minor


 While reading data from sstables, C* does Alder32 checks for any data being read. We have seen that this causes higher CPU usage while doing kernel profiling. These checks might not be useful for digest queries as they will have a different digest in case of corruption.
