Jonathan Ellis commented on CASSANDRA-10540:
--------------------------------------------
While waiting for review, what kind of write amplification improvement (i.e.
total bytes compacted given constant bytes loaded) are you seeing with STCS?

> Key: CASSANDRA-10540
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10540
> Project: Cassandra
> Issue Type: New Feature
> Reporter: Marcus Eriksson
> Assignee: Marcus Eriksson
> Fix For: 3.x

>
> Broken out from CASSANDRA-6696, we should split sstables based on ranges
> during compaction.
> Requirements;
> * dont create tiny sstables - keep them bunched together until a single vnode
> is big enough (configurable how big that is)
> * make it possible to run existing compaction strategies on the per-range
> sstables
> We should probably add a global compaction strategy parameter that states
> whether this should be enabled or not.
