I am using Reactor Kafka, but cannot solve the following problem. Is it possible to configure Receiver to start after the application is fully launched, rather than at the moment with the application? Or, for example, that the Receiver is launched after some event? I couldn't find information about it in the documentation :-(

I wonder how do you launch that receiver at the moment. To be precise there is nothing in Spring Boot which would start consuming from that Kafka receiver automatically. You have to
subscribe()into the resultFluxsomehow in your code. And that is exactly what you can control in your code. For example, you can catch anApplicationReadyEventor have anApplicationRunnerbean. And call some your service which is going tosubscribe()to theFluxfrom receiver.Even Spring for Apache Kafka with its
@KafkaListenerstarts consuming only if the application is fully ready. But Reactor Kafka has nothing to do with Spring. You probably justsubscribe()at some wrong spot.
