Building a recommendation engine, foursquare style

FourSquare has a new post on their developer blog where they describe how they built their recommendation engine for the latest FourSquare 3.0 release. Why do we care? Because FourSquare is a known MongoDB user and of course Mongo is part of their engine. How do they use MongoDB?

Querying an initial corpus to rank – We retrieve a set of venues within the radius you specify as candidate recommendations. For performance reasons, we pull back a fixed number of entries (pro tip: this means that the smaller the radius you set, the more venues we look at per unit area, potentially giving you better results). Given these constraints, we need to have a way of querying our venue database for the top N values sorted by some criteria within a specific geocircle. Most databases simply cannot handle this (at our scale),

MongoSV Review

Fresh off their new funding, 10Gen's MongoSV conference was last Friday. Luckily, I was able to head up to Silicon Valley and attend the event and to see what's new with MongoDB. I'll definitely have more to post about the conference's presentations once the slides and videos become available. But first, a couple of initial thoughts about the conference.

First the event was extremely well organized 10gen's staff did a fantastic job with registration, the event program and scheduling of the presentations. Second, the place was packed; over 500 people attended the event with as many as 100 more on the waiting list trying to get into the event. I was told was the largest conference that they've had out of the previous 12 conferences.

NetFlix Use Case Comparisons

Adrian Cockcroft of NetFlix proposed in a post last week the following use case:

A TV based device calls the API to add a movie to its favorites list (like the Netflix instant queue, but I have simplified the concept here), then reads back the entire list to ensure it is showing the current state. The API does not use cookies, and the load balancer (Amazon Elastic Load Balancer) is round robin, so the second request goes to a different API server, that happens to be in a different Amazon Availability Zone, and needs to respond with the modified list.
