Fix race conditions on one record in Rails: ordered operations, expiring holds, and durable state in your existing SQL database. Solid Objects is a SQL-backed virtual actor library for Ruby on Rails. It brings the Cloudflare Durable Objects programming model to Rails: addressable objects with ordered mailboxes, fenced activation, per-object reminders, transactional effects, and reactive ERB. It runs on MySQL, PostgreSQL, and SQLite without Redis, and requires Ruby 3.3 or newer and Rails 7.1 or newer.
