Marcus Eriksson updated CASSANDRA-16881: ---------------------------------------- Resolution: Duplicate Status: Resolved (was: Open) > L0 compactions never recover when thousands unleveled > ----------------------------------------------------- > > Key: CASSANDRA-16881 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16881 > Project: Cassandra > Issue Type: Improvement > Components: Local/Compaction/STCS > Reporter: Josh McKenzie > Assignee: Josh McKenzie > Priority: Normal > > While this is somewhat mitigated by incremental repair and CASSANDRA-14388, > we can still find ourselves in a scenario where we have thousands of small > sstables living in L0 on STCS and get into a heavily degraded state. > We should add a JMX flag to allow operators to flip the behaviour when doing > STCS in L0 from picking the ‘hottest’ bucket to picking the largest one - > this should allow us to get down to reasonable numbers of sstables in L0 > quicker in this pathological case. If this proves to work particularly well > we could consider making this the default in a future version. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
