Jeff Jirsa commented on CASSANDRA-14796:
----------------------------------------
Sounds like a really useful feature, especially easy since we can already
compact by token range.
> Provide a tool which allows users to force manual compaction by ks.table and
> partition key

> Project: Cassandra
> Issue Type: Wish
> Reporter: Joseph Lynch

> It's somewhat common to have a "hot partition" or otherwise "bad partition"
> that is causing neighbors to fail. In addition to CASSANDRA-12106, I think it
> would be really useful to have an optional partition key argument to
> {{nodetool compact}} (similar to {{getendpoints}}) which would determine
> which sstables a partition resides in (similar to {{getsstables}}) and then
> run manual compaction on just those sstables.
> I know at Netflix a common way that we "mitigate" these bad partitions is to
> delete them, but if the partition is really large it would be nice to be able
> to delete them _and_ then force compaction of sstables containing them.
> Obviously {{gc_grace}} get's in the way but it seems like a cheap/useful tool
> either way.
