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.
