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.)
