Review comment:
I tried to reuse the cache of Datasource tables for Hive tables
InsertIntoStatement for Datasource tables, also fetches from the same cache.
The cache invalidation have been taken care.
From my reading, I didnt find any cases. Let me know if you find any cases
that needs special handling. I will also check the code from this perspective
again.
