Asynchronous processing library for Ruby

Sucker Punch is a single-process Ruby asynchronous processing library. This reduces costs of hosting on a service like Heroku along with the memory footprint of having to maintain additional jobs if hosting on a dedicated server. All queues can run within a single application eg. Rails, Sinatra, etc. process.

Sucker Punch is perfect for asynchronous processes like emailing, data crunching, or social platform manipulation. No reason to hold up a user when you can do these things in the background within the same process as your web application.

Sucker Punch is built on top of concurrent-ruby. Each job is setup as a pool, which equates to its own queue with individual workers working against the jobs. Unlike most other background processing libraries, Sucker Punch’s jobs are stored in memory. The benefit to this is there is no additional infrastructure requirement ie. database, redis, etc.. However, if the web processes are restarted with jobs remaining in the queue, they will be lost. For this reason, Sucker Punch is generally recommended for jobs that are fast and non-mission critical ie. logs, emails, etc..
