Subject [jira] [Commented] (CASSANDRA-8707) Move SegmentedFile, IndexSummary and BloomFilter to utilising RefCounted
Date Tue, 03 Feb 2015 16:54:34 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8707?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14303566#comment-14303566

Joshua McKenzie commented on CASSANDRA-8707:
--------------------------------------------

For the record - I'm vary wary of anything touching SSTableDeletingTask on 2.1 w/regards to
Windows.  That being said - changes there look fine and don't appear to break anything obvious
to my testing over here.  Only thing that popped up with a mixed stress and major compaction
running concurrently was CASSANDRA-8535 as expected.

> There are still a few bugs with resource management, especially around SSTableReader
cleanup, esp. when intermixing with compaction. This migration should help. We can simultaneously
"simplify" the logic in SSTableReader to not track the replacement chain, only to take a new
reference to each of the underlying resources.
