Description

The idea is to break the write pipeline into 2 parts:
1. Before WAL commit
2. After WAL commit
Once that is done, we should always do 2 on a callback to the event when 1 is finished. This will help us in parallelizing multiputs. Currently the multiputs are executed in a serial fashion wherein the order in which the multiputs for different regions are executed is not of a concern.
