> Reduce number of DB calls in ObjectStore::getPartitionsByExprInternal

> Project: Hive
> Issue Type: Improvement
> Components: Metastore
> Reporter: Rajesh Balamohan
> Assignee: Attila Magyar
> Priority: Major
> Attachments: HIVE-23282.1.patch, HIVE-23282.3.patch,

>
> ObjectStore::getPartitionsByExprInternal internally uses Table information
> for getting partitionKeys, table, catalog name.
>
> For this, it ends up populating entire table data from DB (including skew
> column, parameters, sort, bucket cols etc). This makes it a lot more
> expensive call. It would be good to check if MTable itself can be used
> instead of Table.
