Hi @tzulitai, in this particular case, we actually disabled Flink
checkpointing (because we do not want to rely on fixed interval barrier to
trigger sink flush/offset commit). As a workaround, we manually trigger
snapshot and commit upon sink flushing by hooking into source operator's
consumer object. Thus this change. We have also previously discussed this
approach with @StephanEwen
