--------------------------------------
Summary: StatsOptimizer may benefit from fetching stats for
multiple columns at once
Key: HIVE-6289
URL: https://issues.apache.org/jira/browse/HIVE-6289
Project: Hive
Issue Type: Improvement
Components: Metastore, Statistics
Reporter: Sergey Shelukhin
After HIVE-6157, StatsOptimizer would retrieve partition column stats in bulk
for all requisite partitions, but it would still retrieve stats for each column
individually as it does the optimization for that particular column.
It might benefit from batching columns too (APIs for that would exist).
