Marcus Eriksson commented on CASSANDRA-10540:
---------------------------------------------

this patch also needs to handle transient replication (CASSANDRA-14404) - we should split transient ranges evenly over all disks to avoid unbalance

> 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.
