------------------------------------
Reviewer: Igor Guzenko
> Remove old "unmanaged" sort implementation
> ------------------------------------------
>
> Key: DRILL-6832
> URL: https://issues.apache.org/jira/browse/DRILL-6832
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.14.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Minor
> Labels: ready-to-commit
> Fix For: 1.18.0
>
>
> Several releases back Drill introduced a new "managed" external sort that
> enhanced the sort operator's memory management. To be safe, at the time, the
> new version was controlled by an option, with the ability to revert to the
> old version.
> The new version has proven to be stable. The time has come to remove the old
> version.
> * Remove the implementation in {{physical.impl.xsort}}.
> * Move the implementation from {{physical.impl.xsort.managed}} to the parent
> package.
> * Remove the conditional code in the batch creator.
> * Remove the option that allowed disabling the new version.
