Subject [jira] [Commented] (HBASE-17765) Reviving the merge possibility in the CompactingMemStore
Date Mon, 13 Mar 2017 14:41:41 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15907584#comment-15907584
] 

Ted Yu commented on HBASE-17765:
--------------------------------

updateRegionSize is added to swap() as new parameter - without explanation in @param javadoc.
{code}
    if (closeSuffix && region != null) {
{code}
closeSuffix above is changed to updateRegionSize in the patch.

Can you add some comment for the change ?

> According to the new performance results presented in the HBASE-16417 we see that the
read latency of the 90th percentile of the BASIC policy is too big due to the need to traverse
through too many segments in the pipeline. In this JIRA we correct the bug in the merge sizing
calculations and allow pipeline size threshold to be a configurable parameter.
