It was built by Facebook for their services upon principles developed by Google and Amazon for BigTable and Dynamo.
It brings together Dynamo's fully distributed design and Bigtable's ColumnFamily-based data model.
Cassandra is in use at Digg, Facebook, Twitter, Reddit, Rackspace, Cloudkick, Cisco, SimpleGeo, Ooyala, OpenX, and more companies that have large, active data sets. The largest production cluster has over 100 TB of data in over 150 machines.
Data is automatically replicated to multiple nodes for fault-tolerance. Replication across multiple data centers is supported. Failed nodes can be replaced with no downtime.
Every node in the cluster is identical. There are no network bottlenecks. There are no single points of failure.
Cassandra implements an eventually consistent model and includes sophisticated features such as Hinted Handoff and Read Repair to minimize inconsistency windows.
Read and write throughput both increase linearly as new machines are added, with no downtime or interruption to applications.
Allows efficient use for many applications beyond simple key/value.
Writes and reads offer a tunable ConsistencyLevel, all the way from "writes never fail" to "block for all replicas to be readable, " with the quorum level in the middle.
