> Key: HIVE-26721
> URL: https://issues.apache.org/jira/browse/HIVE-26721
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 3.1.2
> Reporter: Yeachan Park
> Priority: Minor
>
> Dropping external tables in hive-metastore with lots of partitions (~30K
> partitions) takes a very long time (~30 minutes)
> This seems strange since external tables should just be a delete operation on
> the metastore database.
> We're running an external hive-metastore with a backend database of Postgres
> 13.7.
