Rails 8 introduces Solid Queue, a new background job processing library designed to eliminate external dependencies by using the database itself for queuing jobs. This approach aims to reduce operational complexity while maintaining performance and reliability for Rails applications.

Why it matters: Solid Queue removes the need for Redis or other external systems, simplifying infrastructure for Rails apps.

The big picture: It supports all Rails-compatible databases and focuses on safety, reliability, and speed, leveraging advanced SQL features like SKIP LOCKED.

The stakes: While simpler, database-backed queuing may bottleneck at scale compared to Redis-based systems like Sidekiq.

Commenters say: Many appreciate the reduced infrastructure complexity but question performance limits and prefer Redis-based tools like Sidekiq for high throughput.
