             Summary: Improve Cache Key
                 Key: HIVE-16879
             Project: Hive

          Components: Metastore
    Affects Versions: 2.1.1, 3.0.0
            Reporter: BELUGA BEHR
            Priority: Trivial

Improve cache key for cache implemented in {{org.apache.hadoop.hive.metastore.AggregateStatsCache}}.

# Cache some of the key components themselves (db name, table name) to conserve memory for
repeated keys and to improve {{equals}} method as now references can be used for equality
# Upgrade _debug_ logging to not generate text unless required
# Changed _equals_ method to check first for the item most likely to be different, column
