> [UI] Don't list all table objects from UI
> -----------------------------------------

> Key: GRIFFIN-195
> URL: https://issues.apache.org/jira/browse/GRIFFIN-195
> Project: Griffin (Incubating)
> Issue Type: Sub-task
> Reporter: Nikolay Sokolov
> Priority: Major
>
> Listing all table objects when rendering list of tables to profile takes lots
> of time, and adds significant latency even if response is cached, when number
> of tables is big and/or schema contains lots of columns.
> Two solutions are possible:
> 1) Without GRIFFIN-194, use DB list API and then list tables API is called
> for each DB, in order to collect all tables. When table is clicked on,
> request to get table details can be made.
> 2) With GRIFFIN-194, DB list followed by number of table list operations can
> be replaced by "list all table names in all databases" operation.
