dhruba borthakur updated HBASE-4989: ------------------------------------ Release Note: The metric fsReadLatency records the number of sequential reads. The metric fsPreadLatency records the number of random reads. Hadoop Flags: Incompatible change Status: Patch Available (was: Open) > Metrics to measure sequential reads and random reads separately > --------------------------------------------------------------- > > Key: HBASE-4989 > URL: https://issues.apache.org/jira/browse/HBASE-4989 > Project: HBase > Issue Type: Improvement > Components: regionserver > Reporter: dhruba borthakur > Assignee: dhruba borthakur > Priority: Minor > Attachments: metrics1.txt > > > HBase does sequential reads for compactions and positional random reads for > satisfying user's queries. It would be nice if we can measure their latencies > separately. It is mostly the random reads that dominate a transactional > workload. -- This message is automatically generated by JIRA.
