Your Ruby snippet is slower for two reasons: - IO.foreach is lazy, but then you call `Array#grep` on it which allocate a huge Array - `grep` populate the "last_match" object, `String#match?` is much faster. Try rifraf&#x2

The capability is there since 2.3 at least, but Matz doesn't want it by default, and prefer to leave it to libraries. If you use bootsnap, you use ".rbc" files already. Source: https://bugs.ruby-lang.org/issue

You also have the Ruby solution of calling a `coerce` [0] method on the right hand side. [0] - https://github.com/ruby/ruby/blob/0703e014713ae92f4c8a2b31e3...

No. That's inaccurate. Shopify is classic multitenant, but sharded.

I work at Shopify. I can confirm that what you are saying is totally false.

This isn't about SSD speed. Reading large file is comparable, but there is a very large overhead on the initial file access because of sandboxing. Opening (or deleting) an empty file is about 2.5x slower on OSX than on a Linux running

This is the app antirez was complaining about: https://github.com/antirez/try.redis It's not even a Rails app. No idea what he was complaining about exactly, but certainly not Rails.

To add to this, most webservers will use `sendfile(2)` for static files.

The ideal process for Shopify’s needs based on the constraints we have to work with (CI speed, deploy speed, rate of changes, etc).

Except that with the amount of activity on the repo it's simply impossible. Every new merge on master would require to rebase several hundred branches being worked on or awaiting reviewed. Multiply this with the hundreds of commits mer

No, even with v1, the merge weren't manual. A bot would merge for you, but directly into master. Now the bot merges into a temporary that is fast-forwarded as the new master if CI validates it.

It was tested. It's simply that between the time you pushed on your branch, and the time you merged, many other commits made it to the master branch, potentially breaking your branch.

No the store doesn't need a supply chain. The distributor who deliver new, filled bottles can take the empty ones back. Which is quite efficient. That's how it works in Quebec for instance.
