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.
