[jira] [Created] (DRILL-7442) Create multi-batch row set reader

Paul Rogers created DRILL-7442:
----------------------------------

             Summary: Create multi-batch row set reader
                 Key: DRILL-7442
                 URL: https://issues.apache.org/jira/browse/DRILL-7442
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Paul Rogers
            Assignee: Paul Rogers


The "row set" work provided a {{RowSetWriter}} and {{RowSetReader}} to write to and read from a single batch. The {{ResultSetLoader}} class provided a writer that spans multiple batches, handling schema changes across batches and so on.

This ticket introduces a reader equivalent, the {{ResultSetReader}} that reads an entire result set of multiple batches, handling schema changes along the way.
