Resolution: Won't Fix
Fix Version/s: (was: 3.x)
> 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
> Labels: performance
>
> 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.
