Subject [jira] [Commented] (CASSANDRA-8707) Move SegmentedFile, IndexSummary and BloomFilter to utilising RefCounted
Date Thu, 05 Feb 2015 15:02:35 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8707?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14307337#comment-14307337

T Jake Luciani commented on CASSANDRA-8707:
-------------------------------------------

I want to give this code time to bake and give users some relief in the meantime with the
other ~100 fixes in 2.1.3. 

I suggest we push this to 2.1.4 as well as CASSANDRA-8683 and CASSANDRA-8744.  I suggest we
disable incremental compaction for 2.1.3 which should avoid most of these bugs.

> 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.
