Joseph Lynch created CASSANDRA-14796:
----------------------------------------
Summary: Provide a tool which allows users to force manual
compaction by ks.table and partition key
Key: CASSANDRA-14796
URL: https://issues.apache.org/jira/browse/CASSANDRA-14796
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.
