---------------------------------------
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.
