> FileSinkOperator can be optimized to run file move operation (/_tmp.-ext --> /-ext-10002) 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).
