paul-rogers commented on issue #1711: DRILL-7011: Support schema in scan
framework
URL: https://github.com/apache/drill/pull/1711#issuecomment-477031299
Added wildcard projection handling for both "lenient" and "strict" schemas.
Added tests for the scan framework. Added a basic tests for "lenient" wildcard
projection with CSV files. Have not yet added CSV tests for strict schema
because I need to know how to pass a table-level property with the new CREATE
SCHEMA command.
