Benedict commented on CASSANDRA-7928: ------------------------------------- WFM :) > 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 > Assignee: sankalp kohli > Priority: Minor > Labels: performance > Fix For: 2.1.1 > > > 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. > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
