Wow, didn't expect this to make a mention on the front page of HN today. I never did convince Etsy to let me deploy bam in production, but it's so simple that it should be doable without much fuss. I mainly built it as a proof-of-concept to show that serving static data does not have to be difficult – and that loading large static data sets into a relational database is a truly wasteful, terrible approach. Are you actually using bam "in anger"?

Bam looks really interesting, definitely a lot simpler than Sparkey, and the basic principle is the same. I have been hesitant to use perfect hashing for Sparkey since I wasn't sure how well it holds up for really large data sets (close to a billion keys). Impressive to write it in less than 300 lines of clean code!
