[jira] [Commented] (CASSANDRA-17774) Implement SSTable count by TWCS bucket

    [ https://issues.apache.org/jira/browse/CASSANDRA-17774?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17571057#comment-17571057 ] 

Paulo Motta commented on CASSANDRA-17774:
-----------------------------------------

Nice feature! Can/should we make this a vtable instead of JMX?

Even though we didn't deprecate JMX yet I think we should favor vtables for new features, unless not practical or fit.

> It should be possible to report the total number of sstables in buckets by using a JMX call {{getSSTableCountPerTWCSBucket()}}, similarly to {{getSSTableCountPerLevel()}}. This will help us to assert the compaction strategy is able to keep up with major compactions on older time buckets.
