> We often hear from users that they want to know when all files in a directory
> (or a GCS Bucket or AWS bucket, etc.) have finished some sort of processing.
> This is difficult to accomplish with the existing processors. NIFI-7476 makes
> it so that a Process Group is able to process a single FlowFile at a time and
> optionally wait until all FlowFiles have finished processing before
> continuing on.
> However, this still doesn't completely resolve this concern because the List*
> Processors create a single FlowFile per object listed. We need the ability to
> list all entities as a single FlowFile. Using a Record Writer allows us to
> accomplish this.
