> The Kafka channel commits the consumer offsets when shutting down (via stop() -> decommissionConsumerAndRecords())
> This can lead to data loss if the channel is shut down while messages have been fetched
in a transaction but the transaction has not yet been committed.
> The only time that the offsets should be committed is when a transaction is complete.
