Thanks for the reporting @melin , actually hoodie already implemented this feature already since release 0.9, we add a metadata field named `__hoodie_operation` to record the per-record change flag. And hoodie can consume CDC and be read a CDC source both through Flink engine already. The spark engine should follow in this feature soon.
But like you said, we should have a more general solution, let's say hoodie would support CDC logs not only for CDC source, but appending logs too, the RFC is coming soon ~
