What is the correct way to make a delay in rabbitmq?

Question

RabbitMQ

I create an order in my project and I need to send it to a third-party api in an hour. Now I'm sending an order to the delay_orders queue that has the x-message-ttl and x-dead-letter-exchange parameters set, which sends orders to the main orders queue with a delay. I found this solution from the article https://habr.com/en/post/338950/. Is this the correct solution or can it be done in a different way? I found the extension https://github.com/rabbitmq/rabbitmq-delayed-messa... but I didn't understand how to install it and it's experimental

Answer 1

The specified solution, in principle, is working (I have met this in my practice), but it is likely that a specialized plugin will work more efficiently (but I won’t say for sure, just an assumption).
The plugin is "under supervision" of the official developers, so there shouldn't be any problems with it. Instructions for installing plugins , the assembled plugin is, for example, here (in the zip archive, the .ez file that RabbitMQ understands).
