Cassandra

Compare

Claimed by Apache Software Foundation Analyzed about 9 hours ago

Cassandra is a highly scalable, eventually consistent, distributed, structured key-value store. Cassandra brings together the distributed systems technologies from Dynamo and the data model from Google's BigTable. Like Dynamo, Cassandra is eventually consistent. Like BigTable, Cassandra provides a ... [More] ColumnFamily-based data model richer than typical key/value systems. Cassandra was open sourced by Facebook in 2008, where it was designed by one of the authors of Amazon's Dynamo. In a lot of ways you can think of Cassandra as Dynamo 2.0. Cassandra is in production use at Facebook but is still under heavy development. [Less]

This has the advantage that you can use new datastore features as soon ... [More] as they get released, and code optimized for the App Engine Datastore can be reused from both Django and WebApp projects. Many optional, useful extras are provided in the companion 'ragendja' library to speed up your App Engine development. [Less]
