Review comment:
Also, I think we should apply the approach proposed in this PR to

https://github.com/apache/spark/blob/62d82b5b270c2eea27ba026e66b7d6598bbaa0a6/sql/core/src/main/scala/org/apache/spark/sql/internal/CatalogImpl.scala#L538-L558
Current implementation is expensive in terms of Hive catalog calls and files
listen. For example, when I started calling the function, it lead to additional
