Subject [jira] [Commented] (HBASE-16608) Introducing the ability to merge ImmutableSegments without copy-compaction or SQM usage
Date Thu, 29 Sep 2016 06:31:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16608?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15531944#comment-15531944

Anoop Sam John commented on HBASE-16608:
----------------------------------------

Thanks for testing Ram.  
bq.Also addIntoPooledChunks now adds from all the segments into one segment. From each segment
there is a chance the pooledChunk is full and you add all those full chunkQueue to another
chunkQueue which at the max can hold chunkPool.getMaxCount().
Ya this is doing nothing with the pool as such.  Each of the merged segments might have N
pooled chunks in its Q.  Now we have merged all these segments into one. We dont refer to
those segments any more. So when the result segment is getting closed some time later, we
will have to release all of these chunks to pool..  This op just put all PooledChunks from
all these segments into one Q. That is the Q in the result Segment.   I dont think some thing
wrong there.
