      Description

      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 with the JIRA. Feel free to comment on the same.
