[jboss-jira] [JBoss JIRA] (JGRP-1319) GMS: view acks on MergeView are only required from partition coordinators

    [ https://issues.jboss.org/browse/JGRP-1319?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12643314#comment-12643314 ] 

Bela Ban commented on JGRP-1319:
--------------------------------

For a merge view {A,B,C,X,Y,Z}, we are already only getting acks from A and X, and only if we use FLUSH.
A then gets acks from its subpartition ({A,B,C} and X from {X,Y,Z}.
No need to change anything...

> When we have a merge of {A,B,C} and {X,Y,Z}, and A and X are the partition coordinators, then view acks for the new combined view {A,B,C,X,Y,Z} will not be received from non coordinator B,C, Y and Z.
> Therefore, as an optimzation, and to avoid spurious warnings, we should get acks for the MergeView only from A and X. A itself will dissemniate the view locally and should only get acks from A,B,C, and X should only get acks from X,Y,Z, too.
