SQLite on Rails: The how and why of optimal performance
Over the last year or so, I have found myself on a journey to deeply understand how to run Rails applications backed by SQLite performantly and resiliently. In that time, I have learned various lessons that I want to share with you all now. I want to walk through where the problems lie, why they exist, and how to resolve them.
Unfortunately, running SQLite on Rails out-of-the-box isn’t viable today. But, with a bit of tweaking and fine-tuning, you can ship a very performant, resilient Rails application with SQLite. And my personal goal for Rails 8 is to make the out-of-the-box experience fully production-ready.
And so, I have spent the last year digging into the details to uncover what the issues are with SQLite on Rails applications as they exist today and how to resolve those issues. So, let me show you everything you need to build a production-ready SQLite-driven Rails application today…
… Yeah, not too bad, huh? These three commands will set your app up for production success. You will get massive performance improvements, additional SQL features, and point-in-time backups. This is how you build a production-ready SQLite on Rails application today.
