Solid Queue
A relational-database-backed background job queue system built into Rails 8. It replaces external dependencies such as Redis and Sidekiq with the database, and uses database transactions to keep jobs and business data consistent.
Timeline (last 90 days)
Rails 8 introduced three database-backed default infrastructure components—Solid Queue, Solid Cache, and Solid Cable—corresponding respectively to the background job queue, the caching layer, and WebSocket broadcasting.
Rails' strategy of building in Solid Queue, Solid Cache, and Solid Cable has pros and cons: supporters believe it lowers the startup cost of new projects, while opponents worry that the expansion of the framework's boundaries brings lock-in effects.
Solid Queue, Solid Cache, and Solid Cable shift the performance pressure of high-frequency read/write scenarios onto the primary database, so in large-scale systems it is still necessary to carefully evaluate whether to switch back to dedicated components.
Rails 8 introduced three major components—Solid Cache, Solid Queue, and Solid Cable—collectively known as the "Solid Trio," which use a database as the backend storage to replace Redis or Memcached.
Solid Queue uses database-level row-locking mechanisms such as SELECT ... FOR UPDATE SKIP LOCKED to implement job dispatch, allowing multiple worker processes to concurrently acquire jobs without lock contention in PostgreSQL and MySQL 8.0+.
