I am pleased to announce that Spring for Apache Kafka 2.7.0 is now available.

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

It is best described with an example:

@RetryableTopic(attempts = "5", backoff = @Backoff(delay = 1000, multiplier = 2.0))
@KafkaListener(id = "sk270", topics = "sk270")
public void listen(String in, @Header(KafkaHeaders.RECEIVED_TOPIC) String topic) {

One of the imperative architectural concerns is to protect APIs and service endpoints from harmful effects, such as denial of service, cascading failure. or overuse of resources. Rate limiting is a technique to control the rate by which an API or a service is consumed. 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…
