> Project: Hive
> Issue Type: Improvement
> Components: Metastore

>
> 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.
