> When establishing HiveSession, it ends up configuring session
> variables/settings.
> As part of it, it ends up checking the database details.
> [https://github.com/apache/hive/blob/master/service/src/java/org/apache/hive/service/cli/session/HiveSessionImpl.java#L314]
> Even if it is `default` DB, it ends up making this check. In corner cases,
> these calls turn out to be expensive.

> We can just skip this check if its `DEFAULT_DATABASE_NAME` (default) DB. This
> may not be an issue for CachedStore.
