Subject [jira] [Commented] (CASSANDRA-8707) Move SegmentedFile, IndexSummary and BloomFilter to utilising RefCounted
Date Wed, 04 Feb 2015 16:28:35 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8707?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14305447#comment-14305447

Benedict commented on CASSANDRA-8707:
-------------------------------------

OK, uploaded a version with all of the outstanding nits addressed and the XManager hierarchy
removed. It doesn't look so ugly, to be honest, so we can definitely manage with this if it
makes it sufficiently clearer. I have my fingers crossed :)

> 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.
