> Project: Hive
> Issue Type: Improvement
> Components: HiveServer2, Standalone Metastore
> Affects Versions: 3.1.0, 4.0.0
> Reporter: Sankar Hariappan
> Assignee: Sankar Hariappan
> Priority: Major
> Labels: Metastore, Performance, pull-request-available

>
> If the partition filter condition has "is not null" then the filter query
> isn't getting pushed to the SQL query in RDMBS.
> This slows down metastore api calls for getting list of partitions with
> filter condition.
> This condition gets added by optimizer in many cases so this is affecting
> many queries.
