> Support for doing partition pruning by passing the partition filter to the database is
added by HIVE-1609. Changing get_partitions_ps to use this could result in performance improvement
 for tables having large number of partitions. A listPartitionNamesByFilter API might be required
for implementing this for use from Hive.
