Beanstalkd vs Que: What are the differences?
Developers describe Beanstalkd as "A simple, fast work queue". Beanstalks's interface is generic, but was originally designed for reducing the latency of page views in high-volume web applications by running time-consuming tasks asynchronously. On the other hand, Que is detailed 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.
Beanstalkd and Que can be categorized as "Background Processing" tools.
Beanstalkd and Que are both open source tools. It seems that Beanstalkd with 5.12K GitHub stars and 748 forks on GitHub has more adoption than Que with 1.47K GitHub stars and 122 GitHub forks.
