I can't wait to ship Sidekiq 8.0's rewritten Sidekiq::Web.

CSS size: 160KB -> 16KB
page rendering: 55ms -> 3ms (!)

Pages should render more or less instantaneously in the browser. Coming in Q1.

“THE TWO BEST RUBY CODEBASES OF ALL TIME: Sidekiq, and Minitest, continual inspirations for style and clarity.” - @nateberkopec

Thanks Nate, I paged thru the minitest code and learned a bunch. For Sidekiq, I recommend starting with sidekiq/api.rb. Lots of value for your time.

Sidekiq 8.0.0.beta1 is officially official and available for testing!

NB: It is *not* useable by Sidekiq Pro/Enterprise customers. OSS only.

Sidekiq 8.0's new Web UI has landed on main. If you feel lucky, give it a test drive and send me any feedback.

You can use the `main` branch by putting this in your Gemfile and running `bundle`:

gem "sidekiq", github: "sidekiq/sidekiq"

Holy cow, it's ALIVE!!!!

I got Sidekiq job profiling working with zero config. Just add `profile: "nonce"` to job options, go to Sidekiq::Web and click View.

Sidekiq metrics win!

It's one thing to build features in the abstract but it's so validating to see users post before/after screenshots.

It is so painful to migrate Sidekiq’s CSS from Bootstrap 3 to Bootstrap 5 that I might just reimplement the whole dang UI from scratch. It’s only a dozen pages. Any UI guru want to pair on it next week? github.com/sidekiq/side...

Doing some benchmarking this morning now that Rails 8 is out and SolidQueue is past 1.0.

Queue 500,000 Active Jobs in SolidQueue/sqlite: 63 seconds (production, log level :warn)

Queue 500,000 Sidekiq::Jobs in Sidekiq: 3.3 seconds

That's only client-side, benchmarking execution is much harder.

I've created Asynq, a new lightweight Sidekiq::Client alternative meant to be safe for use in Ractors.

Herb Lint found a half dozen minor issues with the erb templates in Sidekiq Pro and Enterprise. Fixed! ❤️

Sidekiq 8.0.4 is now available. The major user-visible change? The Web UI is no longer fixed-width.

It turns out monitors can be wider than 1000 pixels. Who knew?

I finally got around to reading "How does Sidekiq really work?" by Dan Svetlov dansvetlov.me/sidekiq-inte.... Dang, it did not disappoint. What an enjoyable and in-depth read! A few things that stuck out to me

2% improvement in Sidekiq's load test, pretty impressive considering this is a macrobenchmark:

json 2.7.2 500,000 jobs in 24.342253 sec, 20540 jobs/sec
json 2.9.1 500,000 jobs in 23.762558 sec, 21041 jobs/sec

Ruby 4.0 warning: it looks like a GC change in 4.0 means Sidekiq may leak memory on every job failure. v8.1.6 will be released tomorrow with a workaround. https://github.com/sidekiq/sidekiq/issues/7006

When a Sidekiq job fails, Sidekiq creates a retry in Redis but it also throws away the entire Processor object and Thread to ensure all jobs execute with "known good state". A Customer reports memo...

Sidekiq 8.0.8 has been released, you can now configure a maximum runtime for iterable jobs to avoid long-running jobs from hogging all threads. 🎹🎶
