Apache Cassandra is an open source distributed database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Cassandra offers robust support for clusters spanning multiple data centers, with asynchronous masterless replication allowing low latency operations for all clients.

Big Data Vectors (3Vs)
- High-Volume
Amount of data such as GB,TB, PB, EB, ZB, YB
- High-Velocity
Speed rate in collecting or Acquiring data
• Generating or processing of data
- High-Variety :
Different data types:

7. Big Data Every Where!
• Lots of data is being collected
and warehoused
– Web data, e-commerce
– purchases at department/
grocery stores
– Bank/Credit Card
transactions
– Social Network
