> 1. Redundant check if table is present or not
> 2. Currently in order to get all constraint form the cachedstore. 6 different
> call is made with in the cached store. Which led to 6 different call to raw
> store
> 3. If constraints are null and valid then also a redundant call is made to
> raw store.
>
> DOD
> 1. Create a flag which tell weather constraint snapshot is valid or not.
> 2. if incremental addition happen to any of the constraint mark snapshot as
> invalid and let updater thread to update cache with valid snapshot data.
> 3. Combine individual constraint call into one call for refresh and creation.
