Best Regards Magnus Reftel -----Opprinnelig melding----- Fra: Bruno Cadonna <br...@confluent.io> Sendt: onsdag 26. februar 2020 17:57 Til: Users <users@kafka.apache.org> Emne: Re: Error handling guarantees in Kafka Streams Hi Magnus, with exactly-once, the producer commits the consumer offsets. Thus, if the producer is not able to successfully commit a transaction, no consumer offsets will be successfully committed, too.
