      Description

      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.)
