> But using events like this requires a very tight integration between event producer and consumer, so I don't think this will translate well to distributed systems or microservices. Though I don't think tight integration between event producer and consumer is necessarily antithetical to microservice design. See the consumer-driven contract pattern, for example: https://www.martinfowler.com/articles/consumerDrivenContracts.html https://www.martinfowler.com/articles/consumerDrivenContract...
