This is a fork of Sidekiq.cr that removes the web and its dependencies.
Sidekiq is a well-regarded background job framework for Ruby. Now we're bringing the awesomeness to Crystal, a Ruby-like language. Why? To give you options. Ruby is friendly and flexible but not terribly fast. Crystal is statically-typed, compiled and very fast but retains a similar syntax to Ruby.
Rough, initial benchmarks on OSX 10.11.5:
| Runtime | RSS | Time | Throughput |
|---|---|---|---|
| MRI 2.3.0 | 50MB | 21.3 | 4,600 jobs/sec |
| MRI/hiredis | 55MB | 19.2 | 5,200 jobs/sec |
| Crystal 0.18.4 | 12MB | 5.9 | 16,900 jobs/sec |
If you have jobs which are CPU-intensive or require very high throughput, Crystal is an excellent alternative to native Ruby extensions. It compiles to a single executable so deployment is much easier than Ruby.
Please see the wiki for in-depth documentation and how to get started using Sidekiq.cr in your own app.
If you use and like this project, please let me know. If demand warrants, I may port Sidekiq Pro and Enterprise functionality to Crystal for sale.
See the issues for chores and other ideas to help.
Things that do not exist and probably won't ever:
- Support for daemonization, pidfiles, log rotation - use Upstart/Systemd
- Delayed extensions - too dynamic for Crystal
The Ruby and Crystal versions of Sidekiq must remain data compatible in Redis. Both versions should be able to create and process jobs from each other. Their APIs are not and should not be identical but rather idiomatic to their respective languages.
