Subject [jira] [Commented] (HBASE-17343) Make Compacting Memstore default in 2.0 with BASIC as the default type
Date Wed, 26 Apr 2017 11:07:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17343?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15984588#comment-15984588

Eshcar Hillel commented on HBASE-17343:
---------------------------------------

bq. I just did a change here like 1st I change the size with increasing (numOfCells * ClassSize.CELL_ARRAY_MAP_ENTRY)
and then only create CellArrayMap and then reduce
How do you think this affects the GC in a way that avoids killing the RS?

Also, in my experiments whenever I used MSLABs I also used the pool. The problem with using
a pool starts in a mixed workload where having a full cache + pool of MSLABs + G1GC is too
much. But I agree this is a subject for a different issue.
