[jboss-jira] [JBoss JIRA] Commented: (JGRP-203) Primary Partiton approach for handling of partitions

[Bela Ban (JIRA)]

Bela Ban commented on JGRP-203:
-------------------------------

I don't see why PRIMARY_PARTITION needs to sort the MergeView is receives: a MergeView is only created by the *merge leader*, and therefore it will be exactly the same on all merge cordinators.
So we don't need to sort it.
A much simpler implementation could be to deterministically find out the primary partition and then send EXIT events to all members in non-primary partitions.
Even simpler: there could be an option in JChannel that triggers an EXIT if we're not in the primary partition on reception of a MergeView. User code could be called to determine the primary partition

> Add this approach to JGroups. Members in a non-primary partition will shut down, become read-only etc.
> Google for "primary partition AND group communication" for the relevant literature on this
