Jeremiah Jordan commented on CASSANDRA-5515: -------------------------------------------- [~thobbs] does CASSANDRA-6010 do what you need? > Track sstable coldness > ---------------------- > > Key: CASSANDRA-5515 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5515 > Project: Cassandra > Issue Type: New Feature > Components: Core > Reporter: Jonathan Ellis > Assignee: Tyler Hobbs > Fix For: 2.0.2 > > Attachments: 0001-Track-row-read-counts-in-SSTR.patch, 5515-2.0-v1.txt > > > Keeping a count of reads per-sstable would allow STCS to automatically ignore > cold data rather than recompacting it constantly with hot data, dramatically > reducing compaction load for typical time series applications and others with > time-correlated access patterns. We would not need a separate age-tiered > compaction strategy. > (This will really be useful in conjunction with CASSANDRA-5514.) -- This message is automatically generated by JIRA.
