When I start to get interested in a project, I usually join the project users mailing list and read it for a couple of months, to get a general feeling of what's going on, what problems do people have, etc…
I became very interested in Cassandra, "A highly scalable, eventually consistent, distributed, structured key-value store".
So, almost 2 months ago, I joined the
cassandra-users mailing list.
Turns out that Cassandra is in production at huge sites like Twitter and Digg. Which doesn't really tell you much if you don't know how they use it, and what they use it for. However, guess what? There's a lot of information out there.
Here's a few links I'd like to share about Cassandra:
- http://wiki.apache.org/cassandra/ArticlesAndPresentations, from the Cassandra wiki, a dense page filled with introductory articles and case studies about the sites I mentioned.
- http://www.parleys.com/#sl=1&st=5&id=1866, video on Cassandra from last February FOSDEM. I was there, but I couldn't see this talk. Too many people.
- http://about.digg.com/node/564, another article by Digg about the NoSQL "movement" in general.
- http://about.digg.com/blog/looking-future-cassandra, an article by a Digg engineer about possible use cases about Cassandra. Note that Digg is using it already, currently.
