Although this command is correct by itself, it won't work in our setup. That's because we've already defined a queue calledhello which is not durable. RabbitMQ doesn't allow you to redefine an existing queue with different parameters and will return an error to any program that tries to...
- Many single-threaded consumers are listening on a single job queue using basic_consume - When a consumer receives a job from the queue, they process it, put the result on a reply queue then ack the message Why use one job queue? If you have multiple queues and use routin...
Giving a queue a name is important when you want to share the queue between producers and consumers, but it's not important if you are using temporary queues. Instead, you should let the server choose a random queue name instead of making up your own names, or modify the RabbitMQ policie...
In the previous tutorial we created a work queue. The assumption behind a work queue is that each task is delivered to exactly one worker. In this part we'll do something completely different -- we'll deliver a message to multiple consumers. This pattern is known as "publish/subscribe". ...
Queues are single-threaded in RabbitMQ, and one queue can handle up to about 50 thousand messages. You will achieve better throughput on a multi-core system if you have multiple queues and consumers and if you have as many queues as cores on the underlying node(s). The RabbitMQ manageme...

application scenario: It takes 10s to process an order, and multiple orders can be placed in the message queue at the same time, and then multiple consumers can be processed at the same time. This is parallel, not the serial situation of a single consumer ...
Events are queued in Kafka topics, and multiple consumers can subscribe to the same topic. Topic are further divided into partitions, which split data across brokers to improve performance. Important features of Kafka include: High volume publish-subscribe messages and streams platform—durable, fast...
