Different systems solve different problems and have different functional characteristics. Actually one of the thing which Kyle highlighted in his report is write cycles (G0 anomaly), it isn't a problem of the Redpanda implementation but a fundamental property of the Kafka protocol. Records in Kafka protocol don't have preconditions and they don't overwrite each other (unlike the database operations) so it doesn't make sense to enforce order on the transactions and it's possible to run them in parallel. It gives enormous performance benefits and doesn't compromise safety.
