With a HoodieDeltaStreamer configured to decode json records, a non-json record causes a failure with no way to skip it or move past. ClickHouse KafkaEngine solves this with an optional "skip invalid records" mode, which seems like it would be helpful here as well.

It's not clear to me if --commit-on-errors is supposed to solve for this, but it appears not to in practice.

On failure, the following stack trace is thrown and the process exits:
