  = 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.
