• A Distributed NoSQL Database
• Google BigTable ✖ Amazon Dynamo
• Continuously Available
• Disaster avoidance, not disaster recovery
• Scale Out with Linear Performance
• Just add nodes
• Run on Commodity Hardware
• In the cloud, on premise, or hybrid
What is Apache Cassandra?
15

19. Company Confidential© 2015 DataStax, All Rights Reserved.
• Fully Distributed
• Data spread over multiple nodes
• All nodes participate in a cluster
• Configurable data replication
• Masterless
• All nodes are equal
• Read from or write to any node
• No Single Point of Failure

Replication Factor – RF
• Specifies how many copies of a row of data C* distributes across nodes
• Highly configurable for SLA and network topology (racks, data centers)
CREATE KEYSPACE "Excalibur" WITH REPLICATION =
{'class' : 'NetworkTopologyStrategy', 'NY1' : 3, 'NY2' : 3};

Consistency Level – CL
• Specifies how synchronized a row of data must be across C* nodes
• Tunable consistency: client application decides CL for each operation
