Sylvain Lebresne updated CASSANDRA-3989:
----------------------------------------
Attachment: 3989.txt
Attaching another approach that makes the compaction type available to the
leveled compaction that for cleanup, scrub and upgradeSSTables simply replace
the old sstable by the new one (without changing level or anything else). The
rational is those operation don't really "change" the sstable content and
should simply "replace" sstables.
> nodetool cleanup/scrub/upgradesstables promotes all sstables to next level
> (LeveledCompaction)

> 1.0.7 + LeveledCompactionStrategy
> If you run nodetool cleanup, scrub, or upgradesstables, Cassandra execute
> compaction for each sstable. During the compaction, it put the new sstable to
> next level of the original sstable. If you run cleanup many times, sstables
> will reached to the highest level, and CASSANDRA-3608 will happens at next
> cleanup.
> Reproduce procedure:
> # create column family CF1 with compaction_strategy=LeveledCompactionStrategy
> and compaction_strategy_options={sstable_size_in_mb: 5};
> # Insert some data into CF1.
> # nodetool flush
> # Verify the sstable is created at L1 in CF1.json
> # nodetool cleanup
> # Verify sstable in L1 is removed and new sstable is created at L2 in CF1.json
> # repeat nodetool cleanup some times
