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.)
