> The ORCWriter's new self tuning feature leads to slower write frequency when
> it comes to ingesting datasets with a low volume of records.
> This is primarily caused by the assumption that the native ORC writer will be
> saturated, which leads to the memory footprint of STRIPE_SIZE +
> avgSizeOfRecord*rowsBetweenMemoryCheck.
> However, this is generally not the case when there are only a few records to
> write due to a low volume dataset, and causes slow writes. We should utilize
> a newer API on ORCWriter brought in by
> [https://github.com/apache/orc/pull/1057]
