Surrogate Keys: Part 2
Devon O'Dell
One of my favorite computer science jokes is that there are only two truly difficult problems in computer science: naming things, cache invalidation, and off-by-one errors. At Fastly, we deal with these sorts of difficult problems every day. In our previous post on surrogate keys, we discussed how this feature can help you solve the problem of invalidating dynamic content. In this post, we’ll take a look under the hood at how we efficiently represented this system.
