Sergey Shelukhin updated HIVE-5234:
-----------------------------------
Description: Some DSes used in name-based partition filtering, as well as
related methods, are suboptimal, which can cost 100-s of ms on large number of
partitions. I noticed while perf testing HIVE-4914, but it can also be applied
separately given that the patch over there will take some time to get in.
