---------------------------------
Summary: Add catalogs to metastore
Key: HIVE-18685
URL: https://issues.apache.org/jira/browse/HIVE-18685
Project: Hive
Issue Type: New Feature
Components: Metastore
Affects Versions: 3.0.0
Reporter: Alan Gates
Assignee: Alan Gates
Attachments: HMS Catalog Design Doc.pdf
SQL supports two levels of namespaces, called in the spec catalogs and schemas
(with schema being equivalent to Hive's database). I propose to add the upper
level of catalog. The attached design doc covers the use cases, requirements,
and brief discussion of how it will be implemented in a backwards compatible
way.
