> Hi,
> According to the dev's list discussion (1) I've patched the CompactionManager
> to allow parallel compaction.
> Mainly it splits the sstables to compact in the desired buckets, configured
> by a new parameter: compaction_parallelism with the current default of "1".
> Then, it just submits the units of work to a new executor and waits for the
> finalization.
> The patch was created in the trunk, so I don't know the exact affected
> version, I assume that is 0.8.
> I'll try to apply this patch to 0.6.X also for my current production
> installation, and then reattach it.
