@vvysotskyi, thanks much for the review and for committing the code. Thanks
also for showing the disassembly of the generated code for the for loops. You
analysis is convincing and I'll change the loops in the next PR.

> Project: Apache Drill
> Issue Type: Improvement
> Reporter: 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.
