Sergey Shelukhin commented on HIVE-11487:
-----------------------------------------
can you use req/resp pattern for a new metastore API? Thrift methods with
"normal" signature can never be modified in any way due to backward compat,
which leads to proliferation of different methods in metastore api
> Add getNumPartitionsByFilter api in metastore api
> -------------------------------------------------

> Adding api for getting number of partitions for a filter will be more optimal
> when we are only interested in the number. getAllPartitions will construct
> all the partition object which can be time consuming and not required.
> Here is a commit we pushed in a forked repo in our organization -
