             Summary: New Compaction for subsequent read's optimisations.
                 Key: HIVE-22701
                 URL: https://issues.apache.org/jira/browse/HIVE-22701

Introducing a new Compaction Type say "OPTIMIZE" to have the following optimizations for better reads:

1. Sort data
2. Re-bucket data
3. z-ordering
4. removing ROW_IDs

I've attached a [design doc| https://docs.google.com/document/d/10zWk7FR6I0CMy57Uykbkcox4HZTMQv2sgLoZrHVeLYU/edit?usp=sharing] with the JIRA. Feel free to comment on the same.
