Description

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.

• is duplicated by: CASSANDRA-9363 Expose vnode to directory assignment
• requires: CASSANDRA-6696 Partition sstables by token range
