-------------------------------
Reviewer: Arina Ielchiieva
> Fixes and improvements to the scan framework for CSV
> ----------------------------------------------------
>
> Key: DRILL-7074
> URL: https://issues.apache.org/jira/browse/DRILL-7074
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.15.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Major
> Fix For: 1.16.0
>
>
> The scan framework is a new set of functionality, based on the result set
> loader, which is in turn based on the row set abstraction. The scan framework
> handles things like batch sizing, projection, null columns, implicit columns
> and more.
> Earlier commits added the basics. This PR refines the framework based on the
> work needed to port the CSV (actually, the "compliant text reader") to the
> framework. To keep PRs of reasonable size, this PR includes only the
> framework changes, the actual revised reader will be in a separate PR.
