Sidekiq

General info:

This repository is a library for background processing for ruby. Background jobs may be hard to maintain and optimize, however, this repository helps users to make these actions easier. Even though some features are only available for those who pay the library but the features they provide free enough for most of the users.

Points of commendation:

• It has very good issue management. Since this library is very popular, it is very likely to find your problem in issue section.
• It has a very good structured wiki section with more than 50 pages.
• Wiki section also have a tutorial for nearly every feature which makes users life easier.
• Since it's a public version of the library, the one can see the tests for features. Sometimes tests can allow developers to see one feature's true potential.
• It has a support for WebUI for tracking the status of background jobs unlike most of the other background management libraries.
• Since it is a public and popular library, it has many add-ons and this library's wiki also list the useful ones for those interested.

Points for consideration:

Some paid features are essential for mid-big companies however the library is expensive. Thus, users may try to find workarounds and this originates compatibility issues when users try to combine the library with another because of the closed nature of the sidekiq.
