I tried to evaluate Kafka usage for event sourcing: <https://github.com/eugene-khyst/ksqldb-event-souring https://github.com/eugene-khyst/ksqldb-event-souring>.

I tried to evaluate Kafka usage for event sourcing: <https://github.com/eugene-khyst/ksqldb-event-souring https://github.com/eugene-khyst/ksqldb-event-souring>. More out of curiosity. But never tried it in production.

Kafka doesn't have a way to assert stream version on event write, which is critical for CQRS. Without it, you can't guarantee stream state when processing a command without resorting to a singleton/locks which does not scale at all. Why Apache doesn't wish to support such a critical feature is beyond me though. https://issues.apache.org/jira/browse/KAFKA-2260 https://issues.apache.org/jira/browse/KAFKA-2260
