Solid Queue Solid Queue replaces the need for not just Redis, but also a separate job-running framework, like Resque, Delayed Job, or Sidekiq, for most people. For high-performance installations, it’s built on the new FOR UPDATE SKIP LOCKED mechanism first introduced in PostgreSQL 9.5, but now also available in MySQL 8.0 and beyond. For more modest needs, it also works with SQLite, which makes it ideal for that no-dependency path to the first HELLO WORLD dopamine hit you get from seeing your work in production right away.
