Class Qualifiers

Class qualifier is the job class pattern. It may match the job class or the job class and method name (when used with ActionMailer delayed deliveries):

• ExampleJob

• Namespaced::ExampleJob

• UserMailer#welcome

You can also use pattern matching:

*

Matches any number of alpha-numeric characters and underscores:

• *Job matches: ExampleJob, but not Namespaced::ExampleJob, or UserMailer#welcome

• UserMailer#* matches any method of UserMailer

**

Matches any number of components:

• ** mathes any job or mailer method

• A::**::Job matches A::B::Job, A::B::C::D::CJob, etc.

• A**::Job matches A::Job, Abc::Job, A::B::Job, etc.

{}

Matches any of the given literal:

• {A,B,C}Job matches AJob, BJob, and CJob

Compatibility

This library aims to support and is tested against:

• Ruby

  • MRI 3.0.x

  • MRI 3.1.x

  • MRI 3.2.x

• Sidekiq

  • 7.2.x

• Redis

  • 6.2.x

  • 7.0.x

  • 7.2.x

If something doesn’t work on one of these versions, it’s a bug.

This library may inadvertently work (or seem to work) on other Ruby, Redis, and Sidekiq versions, however support will only be provided for the versions listed above.

If you would like this library to support another Ruby, Redis, or Sidekiq version, you may volunteer to be a maintainer. Being a maintainer entails making sure all tests run and pass on that implementation. When something breaks on your implementation, you will be responsible for providing patches in a timely fashion. If critical issues for a particular implementation exist at the time of a major release, support for that Ruby, Redis, and/or Sidekiq version may be dropped.
