> 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.
