Nikolay Sokolov updated GRIFFIN-194:
------------------------------------
Description:
Purpose is mainly to support GRIFFIN-195 with single request to get table list
information, while avoiding transferring all table metadata and making lots of
metastore requests.
Hive API provides following relevant APIs right now:
* listing DBs
* getting all table names in DB
* listing all table _objects_ in all _dbs_
What's seems to be missing, is API call for all table names in all DBs (as
middle ground between n+1 API requests and 1 API request with huge payload and
n*m+1 metastore requests on backend).
This api request should take no parameters, and return Map<String,
List<String>> in response.
Proposed API endpoint: TBD
