What it is
A RailsConf 2012 talk by Obie Fernandez, recorded by Confreaks, on practical Redis patterns for Rails apps, drawn from the DueProps codebase.

I'm working on developing an activity stream for a running club I'm working with. Runners will be able to see all the fun and good things that they and their friends have been up to over the past few weeks. Obie Fernandez gave a great talk on how to approach this using Redis at RailsConf 2012 ( the videos on YouTube here [this video] ) and I've adapted this to work within our app. Having run it for a few days, it's clear my next challenge is to build aggregated items into this list now. Take for example the following feed: Here it's clear that the top story would better collapse into something like " Shaun, Alexander and Ivo completed a Group Run...", but this poses an interesting question when t

Also watched a few screencasts like this one: [this video] It seems like a good idea in cases where you want to fetch one object at a time, but it seems like the approach breaks down when you need to show a list of objects along with each of their associations (e.g. in a View or in a JSON response in the case of an API). Whereas in the case of using purely ActiveRecord, you can use includes and eager loading to avoid running N more queries, I can't seem to think of how to do so when depending purely on Redis to model relationships. For instance, s
