Kue - redis backed priority job queue for node.js

coffee-resque and resque work together really well. I didn't mess with the python resque lib much, but I was able to get it to read jobs queued by ruby. With a little work, resque could work as a cross platform queue if you wanted. The main issue I ran into is the way the libs bind resque jobs to objects. For instance, the ruby resque library queues jobs by the ruby class name (Foo::Jobs::Bar), which doesn't translate well to python or node.
A good first step would be defining a spec based on how resque or kue work so that alternate language ports can be written. In the case of resque, other interfaces like its failure or plugin system should also be documented, so that those libs could be ported too.

i agree interface wise it would be interesting, though i think many have slightly different goals and techniques, and frankly they are really basic, but UI-wise it could be neat
Incredibly cool, and thanks for this TJ (as well as your other great work for the Node.js community.)
Have you seen coffee-resque[1], a CoffeeScript interface to the Resque queueing system originally written in Ruby? It's similar, and both Resque (through resque-web) and your app have really nice interfaces. Did you build this because Resque wasn't everything you wanted?

thanks! few reasons:
a) I really wanted the logging / progress indication (haven't seen that personally)
b) I don't read/write coffeescript
c) I don't think coffee-resque has a UI (unless the ruby one works?)Very cool, good to know. Yeah, it seems like it was a simple endeavor—Redis makes creating a queueing system quite easy.
The Ruby `resque-web` interface works and is beautiful[1] with live polling.

ya it's not to shabby, Kue is all live as well.
and also because it really only took less than a day to write, the UI was the primary focus, the rest is really simple
minor typo: A key feature of Kue is it's (should be its) clean user-interface for viewing
One thing I'm not sure about with these job queues - how do you handle cases like having to drop down to C++ to do a chunk of work that cannot be done in JS, without blocking the interpreter?
Or would you just submit that work to a separate external process over something like RabbitMQ, and handle the return when its done?

few ways, you could still utilize child processes of course, so web workers or something. Or just chunk that work up and nextTick() increasing concurrency, OR just increase the total number of workers for more parallelism.
Awesome, and awesome looking interface. Reminds me of Our project Norc, (github.com/darrellsilver/norc). Kue has intermediate statusnof the job, which would be a great feature for Norc.
This look cool.
One question though: How is this different from gearman? Is it the connector with nodejs?
Looks nice, does it support clusters of machines?
yup, I don't see why not, I plan on integrating cluster (one of our projects). each worker uses its own connection with WATCH to implement ZPOP so it should scale fine. we'll certainly need it to :)
Can someone please make this work with Hadoop?
another library from TJ that looks super useful
waves the Node.JS flag
I want to be able to use a job queue as a standard way to communicate between various language backends, so I can use different tools for different jobs. I've started looking into beanstalkd as it has an impressive list of client libraries: https://github.com/kr/beanstalkd/wiki/Client-Libraries.
I'm curious to hear if anyone has any thoughts/experiences/recommendations on using open source job queues to facilitate background processing between different languages and backends. I'm already using redis and resque, something like rabbitmq is overkill, and I just started looking into beanstalkd.
