> Description -
> Problem -
> 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
>
> DOD
> 1. Check only once if table exit in cached store.
> 2. Instead of calling individual constraint in cached store. Add a method
> which return all constraint at once and if data is not consistent then fall
> back to rawstore.
