Andrew Purtell commented on PHOENIX-3789:
-----------------------------------------
We were wrong about rowlock but if we get stuck in postBatchMutate we will hang
other writers and flushes because the MVCC read point is not advanced. Might be
good to still look at this as an improvement.
> 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.
