How we deploy new features. GitHub are experimenting with using Redis for configuration management. I’ve been thinking about this recently too—managing feature flags feels like an ideal use-case for Redis, since it lets you read multiple values on every page access without adding a bunch of extra read traffic on your regular database. # 8th July 2010, 10:04 am

I asked in their comments if they’d considered trying to run the upgrade with no downtime at all using Redis replication, and Ryan Tomayko has posted some interesting replies. # 28th May 2010, 2:50 pm

Introducing Resque. A new background worker management queue developed at GitHub, using Redis for the persistence layer.

How We Made GitHub Fast. Detailed overview of the new GitHub architecture. It’s a lot more complicated than I would have expected—lots of moving parts are involved in ensuring they can scale horizontally when they need to. Interesting components include nginx, Unicorn, Rails, DRBD, HAProxy, Redis, Erlang, memcached, SSH, git and a bunch of interesting new open source projects produced by the GitHub team such as BERT/Ernie and ProxyMachine. # 21st October 2009, 9:14 pm
