📌 Overview Ruby on Rails has helped make it possible to scale out the database layer, meeting the demands of millions of Aura Frames customers enjoying their digital photo frames. In late 2025, the team added additional primary databases to expand capacity for peak write and read load ahead of Christmas Day, the busiest day of the year for the company. Rails manages queries and schema changes for each primary database within the same codebase, and now with the additional capacity of many primary databases. With 8 primary databases in total, each server instance can be vertically scaled ahead of peak load. When load returns to normal levels, instances are scaled down for cost savings. The team leveraged native support for Multiple Databases and the disable_joins: true feature in Active Record, the ORM for Ruby on Rails. The disable_joins feature replaces SQL joins, issuing multiple SELECT statements to combine data in the application from different databases. This post looks back at the technical details of that plan, as well as a variety of additional data layer scaling tactics, that culminated in a successful Christmas 2025 season, with peak U.S. and Canadian Apple App Store and Google Play Store rankings of #1.

This post was originally given as a talk at Rubycon IT 2026. The slides are also available. It’s been a while since I first talked about rv, a Ruby manager for the future. I’d like give an update on what we’ve done since then, but I’m going to recap some of that earlier post first to give context for the updates. If you still remember what I said back then, you can jump to the new stuff right away. Either way, I’m excited to update you about the work that we’ve been doing, and show exactly how far we’ve gotten.

In this essay, Carson Gross argues that as AI makes code cheap to produce, understanding code becomes the expensive and scarce resource. He warns of the complexity that LLM code can generate and proposes the subtractive, constraining engineer as the discipline needed to keep systems comprehensible & stable.
