Victoria Markman commented on DRILL-4236:
-----------------------------------------
I agree that it's a separate bug and I was combing jira to find existing bug,
because it's always been the case that sort could run out of memory in some
specific conditions.
Is this something we are going to fix for 1.5.0 and hold release for ?
> 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
> Labels: documentation
> 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.
