Paul Yang commented on HIVE-1609:
---------------------------------
A couple of suggestions:
1. Update get_partitions_ps() to use get_partitions_by_filter(). By doing this,
we should see some speedup when using the Hive CLI for tables with large number
of partitions. (May require #2 for full benefits)
2. could we add a listPartitionNamesByFilter() as well to RawStore/ObjectStore?
This would allow partition filtering for get_partition_names_ps(). This could
be done in a separate JIRA, if necessary.
3. Add test cases to TestHiveMetastore for the new method(s).
I'll take another look once the antlr stuff is done, but looks good.

> The metastore needs to have support for returning a list of partitions based
> on user specified filter conditions. This will be useful for tools which need
> to do partition pruning. Howl is one such use case. The way partition pruning
> is done during hive query execution need not be changed.
