Apache Cassandra Wiki

{{{#!wiki red/solid Most of the information in this Wiki is being deprecated!

The official Cassandra documentation is located here. Cassandra is moving away from this wiki for user-facing documentation in favor of in-tree docs. Patches to the official in-tree documentation are welcome and can be submitted via a GitHub Pull Request.

This wiki is intended instead to document Cassandra internals and how to edit them and thus contains developer-focused information. If you really need access to this wiki, please send an email to the mailing list dev@cassandra.apache.org with your wiki username and we will add you.

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.
