--------------------------------------

             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).
