------------------------------------------
Summary: Database should have a unique id
Key: HIVE-23785
URL: https://issues.apache.org/jira/browse/HIVE-23785
Project: Hive
Issue Type: Improvement
Reporter: Vihang Karajgaonkar
Assignee: Vihang Karajgaonkar
HIVE-20556 introduced a id field to the Table object. This is a useful
information since a table which is dropped and recreated with the same name
will have a different Id. If a HMS client is caching such table object, it can
be used to determine if the table which is present on the client-side matches
with the one in the HMS.
We can expand this idea to other HMS objects like Database, Catalogs and
Partitions and add a new id field.
