> This help in following ways:-
> 1. Without checkpointing, if any point of time, hbase is restarted or Index rebuilding
fails, then we need to start all over again.
> 2. Avoid starvation of small lag of indexes by rebuild of larger lag of other index.
> 3. And ,with checkpointing , we can stop automatic rebuilding of indexes if user requested
REBUILD ASYNC in between.
