Even Sourcing is nice on paper but when having a few service you will feel pain if not do it properly. We had applications listen to topics on Kafka and can re-play to process the message. All sound goods. When we started to add more topics, we realize we no longer know who own the topic and subscribe to the topic. We no longer feel safe to just drop a topic and have to grep/search around, however lots of these information is configured in environment variable, and sometime pull from our config management system such as Vault/K8S config make it even harder to grep because we have to export data out of these system and grep I think event sourcing is nice and powerful but hard to done well.
