> = Background =
> 
> Development of Cassandra started in Facebook in June 2007. It started of a 
> system to solve the Inbox Search problem and since then has
> matured to solve various storage problems associated with 
> structured/unstructured data.
> 
> = Rationale =
> 
> Cassandra is a distributed storage system for managing structured data that is 
> designed to scale to a very large size across many commodity servers, with no 
> single point of failure.
> The philosophy behind the design of the storage portion of Cassandra is that it 
> be able to satisfy the requirements of applications that demand storage of large 
> amounts of structured data. Reliability at massive scale is a very big 
> challenge. Outages in the service can have significant negative impact. Hence 
> Cassandra aims to run on top of an infrastructure of hundreds of nodes  
> (possibly spread across different datacenters). At this scale, small and large 
> components fail continuously; the way Cassandra manages the persistent state in 
> the face of these failures drives the reliability and scalability of the 
> software systems relying on this service.

> Intial Source can be obtained from the following site -

> == Relationships with Other Apache Products ==
> * The Cassandra project is 'similar' to hbase/HDFS in concept, but Cassandra is

> == An excessive fascination with the Apache brand ==
