A deep dive into Solid Cable

When Action Cable was introduced, running Redis in production became the norm. But with the introduction of Solid Queue and Solid Cache, Redis became almost optional. Almost. With Rails 8, Solid Cable became part of the Solid family, making it possible to deploy many Rails apps to production without Redis. In this talk, we'll explore Solid Cable's internals, why it was created, how it compares to the other Action Cable adapters, and where realtime Rails apps are headed in the age of LLM interfaces.
