---------------------------------
Summary: Cache table constraints in CachedStore
Key: HIVE-22015
URL: https://issues.apache.org/jira/browse/HIVE-22015
Project: Hive
Issue Type: Sub-task
Reporter: Daniel Dai
Currently table constraints are not cached. Hive will pull all constraints from
tables involved in query, which results multiple db reads (including
get_primary_keys, get_foreign_keys, get_unique_constraints, etc). The effort to
cache this is small as it's just another table component.
