Subject [jira] [Created] (CASSANDRA-11035) Use cardinality estimation to pick better compaction candidates for STCS (SizeTieredCompactionStrategy)
Date Tue, 19 Jan 2016 22:15:40 GMT
Wei Deng created CASSANDRA-11035:
------------------------------------

             Summary: Use cardinality estimation to pick better compaction candidates for
STCS (SizeTieredCompactionStrategy)
                 Key: CASSANDRA-11035
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11035
             Project: Cassandra
          Issue Type: Improvement
          Components: Compaction
            Reporter: Wei Deng


This was initially mentioned in this blog post http://www.datastax.com/dev/blog/improving-compaction-in-cassandra-with-cardinality-estimation
but I couldn't find any existing JIRA for it. As stated by [~jbellis], "Potentially even more
useful would be using cardinality estimation to pick better compaction candidates. Instead
of blindly merging sstables of a similar size a la SizeTieredCompactionStrategy." The L0 STCS
in LCS should benefit as well.
