> Hadoop input/output formats currently can OOM on wide rows.
> We can add a new option to the ConfigHelper like columnPagingSize with a default of Integer.MAX_VALUE.
> The input format would page the row internally rather than pull it over at once.
> The output format could also use this to avoid sending huge rows over at once.
