Subject [jira] [Commented] (PHOENIX-3789) Execute cross region index maintenance calls in postBatchMutateIndispensably
Date Mon, 17 Apr 2017 19:21:41 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-3789?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15971519#comment-15971519
] 

James Taylor commented on PHOENIX-3789:
---------------------------------------

We might need to write any index updates that are local to this RS still in the postBatchMutate.
Updates that go across to other RSs may be ok in the postBatchMutateIndispensably. Just a
theory.

> Making cross region server calls while the row is locked can lead to a greater chance
of resource starvation. We can use the postBatchMutateIndispensably hook instead of the postBatchMutate
call for our processing.
