----------------------------------
Summary: Refactor "managed" external sort for unit tests
Key: DRILL-5342
URL: https://issues.apache.org/jira/browse/DRILL-5342
Project: Apache Drill
Issue Type: Sub-task
Affects Versions: 1.10.0
Reporter: Paul Rogers
Assignee: Paul Rogers
Fix For: 1.11.0
The external sort was heavily refactored in 1.10 to allow adding memory
management. (See DRILL-5080.) That effort focused on breaking up the large
functions into smaller chunks to allow us to more easily modify the bits
relevant to adding memory management.
This ticket discusses refining those changes to create modular bits that can be
unit tested individually. For the most part, code will remain unchanged
functionally, but functions will shift from class to class to break
dependencies. Also, interfaces will be narrowed to remove global dependencies
on things like {{FragmentContext}} or {{OperatorContext}}.
The code reviewer(s), when using GitHub, will simply see large changes. Notes
below identify what was actually changed vs. what was merely moved.
