Need for speed

When it comes to driving, I'm a rather slow driver. I can parallel park with my eyes-closed, merge in traffic easily, but I really don't enjoy driving fast (Mind you, I take public transport these days). But when it comes to squeezing performance out of a system, I guess I'm much more attracted to the idea of things running fast. The redis attraction is therefore quite obvious. In-memory database. It doesn't get much faster than that.

Bumps on the road

It was rather surprising to come across speed issues with redis, and fairly early-on with our project. At kenHub, we are building an anatomy learning platform. The platform must adapt to each and every student, and present them with the best question for their level. To do this, we must store statistics for each and every anatomy term for each user.
