Que vs Resque: What are the differences?
Developers describe Que as "A Ruby job queue that uses PostgreSQL's advisory locks for speed and reliability". Que is a high-performance alternative to DelayedJob or QueueClassic that improves the reliability of your application by protecting your jobs with the same ACID guarantees as the rest of your data. On the other hand, Resque is detailed as "A Redis-backed Ruby library for creating background jobs, placing them on multiple queues, and processing them later". Background jobs can be any Ruby class or module that responds to perform. Your existing classes can easily be converted to background jobs or you can create new classes specifically to do work. Or, you can do both.
Que and Resque belong to "Background Processing" category of the tech stack.
Que and Resque are both open source tools. Resque with 8.54K GitHub stars and 1.57K forks on GitHub appears to be more popular than Que with 1.47K GitHub stars and 122 GitHub forks.
