问题 From spring boot tutorial: https://spring.io/guides/gs/messaging-rabbitmq/ They give an example of creating 1 queue and 1 queue only, but, what if I want to be able to create more then 1 queue? how would it be possible? Obviously, I can't just create the same bean twice: @Bean Queue queue() { return new Queue(queueNameAAA, false); } @Bean Queue queue() { return new Queue(queueNameBBB, false); } You can't create the same bean twice, it will make ambiguous. 回答1: Give the bean definition factory

问题 We are building a solution in which we are publishing message to a time-out queue. After TTL expiry messages are pushed to main queue for re-processing. We are setting up counter value so that messages will be tried for x no. of times for the redelivery. Solution is working fine. But the scenario is when the message on the head position is highest TTL is not expired, other messages of lower expiry will not be re-published (to main queue). Is this understanding correct ? If Yes what is the

问题 I've been looking at MassTransit for a couple of weeks now and I'm curious about the possibilities. However, I don't seem to be able to get the concepts quite right. Expected behaviour I wanted to publish message to "direct" exchange with routing key which is bind to two different queue for performing other activities. When I attempted the same logic using MassTransit for better scalability. I've found MassTransit creates own exchange based on queue name with fanout type. Classic code to

问题 It seems like the worker pattern, fanout, and filtered topics can all be implemented with topic exchanges. Why would I ever use a direct or fanout exchange instead? We would like to codify common patterns found in our org in a library that abstracts the infinite flexibility of amqp (naming conventions, defaulting to durable, sending common headers, expirations etc.). Should we leverage the different exchange types or implement all patterns with topics; why? (We have consumers/publishers in

问题 Let's say that I have a pipeline of commands that need to be executed sequentially and that some of the commands contain multiple operations that should be executed in parallel (same correlation id). And let's assume that I need to know when all parallel operations are executed in order to proceed with execution further in the pipeline. Is it possible to achieve this kind of orchestration with RabbitMQ alone by using exchanges and queues without usage of external data sources like database ?

问题 I'm trying to install rabbitmq via puppet. I'm using the puppetlabs-rabbitmq module. It also has section to configure queues and exchanges, which are Native Types . I can't figure out how to use these native types. My code for rabbitmq installation: class rabbitmq-concrete{ $tools = ["vim-enhanced","mc"] package { $tools: ensure => "installed" } $interface = "enp0s8" $address = inline_template("<%= scope.lookupvar('::ipaddress_${interface}') -%>") class { 'rabbitmq': config_cluster => true,
