> Currently, operators make no distinction between closing (which needs to emit remaining buffered data) and disposing (releasing resources).
> In case of a failure, we want to only release the resources, and not attempt to send pending buffered data.
> Effectively, streaming operators need to implement these methods then:
>   - open()
>   - processRecord()
>   - processWatermark()
>   - close()
>   - dispose()
