Deneche A. Hakim created DRILL-4236:
---------------------------------------

             Summary: ExternalSort should use the new allocator functionality to better manage
it's memory usage
                 Key: DRILL-4236
                 URL: https://issues.apache.org/jira/browse/DRILL-4236
             Project: Apache Drill
          Issue Type: Improvement
          Components: Execution - Relational Operators
    Affects Versions: 1.5.0
            Reporter: Deneche A. Hakim
            Assignee: Deneche A. Hakim
             Fix For: 1.5.0


Before DRILL-4215, the sort operator wasn't able to correctly compute it's memory usage, and
so it jumped through a bunch of hoops to try to figure out when it should spill to disk.
With the transfer accounting in place, this code can be greatly simplified to just use the
current operator memory allocation.
