Alan Gates commented on HIVE-18685:
-----------------------------------
{quote}Your document doesn't describe any restrictions on catalog name - should
it be limited by size or allowed character set?
{quote}
I was assuming the same sorts of restrictions we have on database and table
names, but I can make that explicit in the document.
> 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
> Priority: Major
> 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.
