> 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
