If you would like to contribute to this wiki, please send an email to the mailing list dev.at.cassandra.apache-dot-org with your wiki username and we will be happy to add you. Contributions welcome!
Cassandra is a highly scalable, eventually consistent, distributed, structured key-value store. Cassandra brings together the distributed systems technologies from Dynamo and the log-structured storage engine from Google's BigTable.
Cassandra is moving away from this wiki for user-facing documentation in favor of in-tree docs, linked below. (Pull requests welcome!)
Developer-focused information is still hosted on the wiki; see below.
