Hi group: I'm working for building a webhook notification service based on Kafka. I produce all of the payloads into Kafka, and consumers consume these payloads by offset.
Sometimes some payloads cannot be consumed because of network exception or http server exception. So I want to mark the failed payloads and retry them by timers. But I have no idea if I don't use a storage (like MySQL) except kafka and zookeeper. -- *noodles!*
