--------------------------------------
Summary: partition name filtering uses suboptimal datastructures
Key: HIVE-5234
URL: https://issues.apache.org/jira/browse/HIVE-5234
Project: Hive
Issue Type: Improvement
Reporter: Sergey Shelukhin
Assignee: Sergey Shelukhin
Some DSes used in name-based partition filtering, as well as related methods,
are suboptimal, which can cost 100s 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.
