Alexander Kolbasov commented on SENTRY-2304:
--------------------------------------------
A simple WHERE clause for DB name doesn't make things slower and all tables for
all DBs may be pretty large list for some installations.
> Optimize the time taken for HMS snapshot creation.

> Key: SENTRY-2304
> URL: https://issues.apache.org/jira/browse/SENTRY-2304
> Project: Sentry
> Issue Type: Sub-task
> Components: Sentry
> Affects Versions: 2.1.0
> Reporter: kalyan kumar kalvagadda
> Priority: Major
>
> First get all the database names and their locations.
> # Create Table Task for each database by providing the db name
> # DB Task will get the names and locations for all the tables in that
> database.
> # Create Partition task for each table in that database by providing the
> database and table names.
> ## Table task will get the locations of all the partitions in that table.
> This approach needs new API’s implemented in HMS to get the names and
> locations of the databases/tables/partitions.
