> Issue Type: Improvement
> Components: Catalog

>
> Currently builtins_db is created in the catalogd initialization. But later on
> when catalogd calls reset(), catalogd will replace its dbCache with DBs from
> HMS. As a result, a delete builtins_db operation is always in the initial
> catalog update sent to statestore. Though statestore doesn't send it to
> impalad because the initial catalog is not a delta and doesn't include delete
> operations, it's a potential problem. We should remove builtins db from
> catalogd because it's not needed there.
