Alex Deparvu commented on CASSANDRA-14888: ------------------------------------------ thanks [~djoshi] for the discussion. I agree with the minimal approach, but there was a fair amount of shuffle, mainly contained inside the TableMetrics class. I pushed a new version of the patch, let me know what you think. [0] Changes: * TableMetrics: I tried to aggregate all registered metrics into the 'all' set, which now contains 'release' wrappers for each registered metric. it was a bit of a stretch, so if there's a way to make the code cleaner I'm open to further changing it. * KeyspaceMetrics: this was a much simpler setup, most changes are trivial refactoring of functions. release happens automatically thanks to the factory keeping track of registered metrics. * added some tests covering metrics unregistering for tables and keyspaces [0] https://github.com/apache/cassandra/compare/trunk...stillalex:CASSANDRA-14888 > Several mbeans are not unregistered when dropping a keyspace and table > ---------------------------------------------------------------------- > > Key: CASSANDRA-14888 > URL: https://issues.apache.org/jira/browse/CASSANDRA-14888 > Project: Cassandra > Issue Type: Bug > Components: Observability/Metrics > Reporter: Ariel Weisberg > Assignee: Alex Deparvu > Priority: Urgent > Labels: patch-available > Fix For: 4.0, 4.0-rc > > Attachments: CASSANDRA-14888.patch > > > CasCommit, CasPrepare, CasPropose, ReadRepairRequests, > ShortReadProtectionRequests, AntiCompactionTime, BytesValidated, > PartitionsValidated, RepairPrepareTime, RepairSyncTime, > RepairedDataInconsistencies, ViewLockAcquireTime, ViewReadTime, > WriteFailedIdealCL > Basically for 3 years people haven't known what they are doing because the > entire thing is kind of obscure.
