>
> 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.
