Rajesh Balamohan created HIVE-13922:
---------------------------------------

             Summary: Optimize the code path that analyzes/updates col stats
                 Key: HIVE-13922
                 URL: https://issues.apache.org/jira/browse/HIVE-13922
             Project: Hive
          Issue Type: Improvement
          Components: Metastore
            Reporter: Rajesh Balamohan
            Priority: Minor


1. Depending on the number of partitions, HiveMetastore::update_partition_column_statistics::getPartValsFromName obtains the same table several times.

2. In ObjectStore, number of get calls to obtain the column stats can be considerably reduced when writing table/partition stats.
