Matt Burgess commented on NIFI-4491:
------------------------------------
Agreed, with the caveat that an outgoing record-based FlowFile should contain a
single transaction if possible and prudent, regardless of the number of records
within, in order to preserve behavior between source and target DBs.
> Make CaptureChangeMySQL a record-aware processor

> Key: NIFI-4491
> URL: https://issues.apache.org/jira/browse/NIFI-4491
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Matt Burgess
> Priority: Major
>
> 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.
