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.

> Execute cross region index maintenance calls in postBatchMutateIndispensably

> 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.
