  Cassandra is a highly scalable, eventually consistent, distributed, 
structured key-value store. Cassandra brings together the distributed systems 
technologies from 
[http://s3.amazonaws.com/AllThingsDistributed/sosp/amazon-dynamo-sosp2007.pdf 
Dynamo] and the data model from Google's 
[http://labs.google.com/papers/bigtable-osdi06.pdf BigTable]. Like Dynamo, 
Cassandra is

of the authors of Amazon's Dynamo. In a lot of ways you can think of Cassandra

+ Cassandra was open sourced by Facebook in 2008, where it was designed by 
Avinash Lakshman (one of the authors of Amazon's Dynamo) and Prashant Malik ( 
Facebook Engineer ). In a lot of ways you can think of Cassandra as Dynamo 2.0 
or a marriage of Dynamo and BigTable.  Cassandra is in production use at 
Facebook but is still under heavy development.
