> FileSinkOperator can be optimized to run file move operation (/_tmp.-ext -->
> /-ext-) in parallel fashion. Currently it invokes
> {{Utilities.moveSpecifiedFileStatus}} and renames in sequential mode causing
> delays in cloud storage. FS rename can be used (S3A internally has parallel
> rename operation).
