Background Tasks in Node.js: A survey with Redis.
Evan Tahler

Thank you for these explanations and the node-resque package. Coming from RoR background using Resque to being a newbie in Node.js (in general and specifically with Resque) was a very easy transition.

Just a questions about delayed (future) tasks: I understand that in order to process such a task the Scheduler polls Redis every X seconds and that only a single master is allowed to do so. Doesn’t that create a bottleneck on a single instance to poll those? Can’t it poll similar to the way the “regular” tasks are being polled to distribute the work?

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
