Subject [jira] [Commented] (HBASE-14613) Remove MemStoreChunkPool?
Date Fri, 16 Oct 2015 05:39:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14613?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14960206#comment-14960206

Lars Hofhansl commented on HBASE-14613:
---------------------------------------

I am always dubious about trying to be smarter than the GC. Extra management, the requirement
to get the number of chunks right to be useful but not wasteful, etc.

> I just stumbled across MemStoreChunkPool. The idea behind is to reuse chunks of allocations
rather than letting the GC handle this.
> Now, it's off by default, and it seems to me to be of dubious value. I'd recommend just
removing it.
