             Summary: Refactor ColumnWriter to simplify type-conversion shim
                 Key: DRILL-7024
                 URL: https://issues.apache.org/jira/browse/DRILL-7024
             Project: Apache Drill
          Issue Type: Improvement
    Affects Versions: 1.15.0
            Reporter: Paul Rogers
            Assignee: Paul Rogers


DRILL-7006 added a type conversion "shim" within the row set framework. Basically, we insert a "shim" column writer that takes data in one form (String, say), and does reader-specific conversions to a target format (INT, say).

The code works fine, but the shim class ends up needing to override a bunch of methods which it then passes along to the base writer.

This ticket asks to refactor the code so that the conversion shim is simpler.
