[jira] [Created] (HIVE-10393) Make AddPartitionMessage and DropPartitionMessage leaner

Sushanth Sowmyan created HIVE-10393:
---------------------------------------

             Summary: Make AddPartitionMessage and DropPartitionMessage leaner
                 Key: HIVE-10393
                 URL: https://issues.apache.org/jira/browse/HIVE-10393
             Project: Hive
          Issue Type: Bug
            Reporter: Sushanth Sowmyan


AddPartitionMessage and DropPartitionMessage currently contain a List<Map<String,String>> ptnKeyValues to store a list of partitions, each by its set of key-values. This results in a lot of duplication, since the partition keys are the same across them.

So, we should split that into two getters:

a) List<String> getPtnKeys
b) List<List<String>> getPtnPartVals

That way we store the entire info, but for larger messages, cut the storage required nearly by half.
