Cassandra at Gowalla « The Real Adam

We have a few motivations for using Cassandra at Gowalla. First off, it’s become out database of choice for applications with relatively fixed query patterns that, for us to succeed, need to handle a rapidly growing dataset. Cassandra’s read and write paths are optimized for these kinds of applications. It’s good at keeping the hot subset of a database in memory while keeping queries that require hitting disk pretty quick too.

Cassandra is also great for time-oriented applications. Any time we need to fetch data based primarily on some sort of timestamp, Cassandra is a great fit. It’s a bit unique in this regard, and that’s one of the main reasons I’m so interested in Cassandra
