David Handermann commented on NIFI-4491:
----------------------------------------

Commenting on this issue for future reference, it seems best to create a new 
record-oriented Processor as opposed to implemented record-oriented processing 
in CaptureChangeMySQL. Handling large numbers of binary log events is not 
optimal for framework processing, so a new record-oriented version could 
provide a recommend way forward that would enable deprecation of the current 
Processor for eventual removal.

> The main reason CaptureChangeMySQL doesn't leverage the RecordSetWriter API 
> is that those capabilities were being developed in parallel with that 
> processor. Whether a new record-aware processor is better than an improvement 
> to the original is up for discussion; however, it would be a good idea to 
> support the RecordSetWriter API for any CDC (CaptureChangeXYZ) processor.
