This release contains a significant enhancement, which is a community contribution. Failed deliveries can be forwarded to a series of topics for delayed redelivery.

@KafkaListener(id = "sk270", topics = "sk270")
public void listen(String in, @Header(KafkaHeaders.RECEIVED_TOPIC) String topic) {
    LOG.info(in + " from " + topic);
    throw new RuntimeException("test");
}

@DltHandler

In a distributed system, no better option exists than to centralize configuring and managing the rate at which consumers can interact with APIs. Only those requests within a defined rate would make it to the API. Any more would raise an HTTP “Many requests” error.

Spring Cloud Gateway (SCG) is a simple and lightweight component…
