Yep, I wished I had had access to this back when I was working on something in the Rails side. Ingesting large amounts of data from Shopify across multiple oauth access points while being limited to the PostgreSQL backend and Shopify rate limit restrictions was a pain to setup with Redis and Sidekiq. I ended up forking Sidekiq to accomplish that -- essentially using Sidekiq as a concurrency framework to build in a different set of behavior. Reading through the GenStage document, I could have implemented something better. The way I implemented it (with Ruby) left gaps of idle time, and huge amounts of data gets staged through the queues. I couldn't figure out how to make it better. Since I only had a week to come up with something while the infrastructure was melting down, at the time, it was acceptable. Looking at this though, the demand-based backpressure would work very well. There are a couple problems I think I can use this in my current work -- this is great work!
