如何在Kafka中创建用于延迟重发消息的结构

Question

Delay producing the message to the topic? If not, will it appear soon?

I have "NQueue" topic for sending differents notifications(Sms, Push, Transactions). I am trying turn a failed message(HttpRequest) back to queue with some delay.

I have already re-read all the documentation and have not found this functionality. If it does exist, or you know how to implement it, then write here, please.

Like:

await producer.ProduceAsync(topic, message, delay);

Below I will attach a photo of my vision...

If you are considering the use of Kafka Stream , I would suggest to consider the option of using windowed aggregations . In short, as follows:

• create a Kafka topic for failed messages
• build a Kafka Stream app with windowed aggregations to turn failed messages back to your queue (also be aware of an ability to suppress consecutive updates ). I assume that windowed aggregations will give you the opportunity to delay your failed messages.

In case streams are not suitable for you, look at the Dead Letter Queues
