Subject RE: Using DTCS, TTL but old SSTables not being removed
Date Tue, 15 Sep 2015 07:26:55 GMT
Hi,

Any idea when 2.2.2 will be released?
I see there are still 3 issues left to fix:
https://issues.apache.org/jira/browse/CASSANDRA/fixforversion/12333319/?selectedTab=com.atlassian.jira.jira-projects-plugin:version-summary-panel

Subject: Re: Using DTCS, TTL but old SSTables not being removed

2.2.1 has a pretty significant bug in compaction: https://issues.apache.org/jira/browse/CASSANDRA-10270

That prevents it from compacting files after 60 minutes. It may or may not be the cause of
the problem you’re seeing, but it seems like it may be possibly related, and you can try
the workaround in that ticket to see if it helps.
