Introducing Practical RabbitMQ (php[tek] 2016 - Tutorial)
4 likes876 views
In this tutorial, I will introduce RabbitMQ as a solution to scalable, interoperable, flexible applications. This tutorial is perfect for those who want to dive deep into RabbitMQ with little or no pre-existing knowledge about message queuing systems. Once you have finished the tutorial, you will know how to set up basic publish/subscribe message queues, control the flow of messages using various exchanges, and understand various features of RabbitMQ, such as RPC, TTL, and DLX.
