Job queues, message queues and other queues. Almost all of them in one place.
There are many queueing systems out there. Each one of them is different and was created for solving certain problems. This page tries to collect the libraries that are widely popular and have a successful record of running on (big) production systems.
Feel free to add more resources to this page or clean it up!
