Jonathan Ellis created CASSANDRA-5515: -----------------------------------------
Summary: 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 Fix For: 2.0 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.
