Apache Cassandra

Apache Cassandra. It is a non-relational, non- SQL data manager . It uses a style called BigTable and is designed to save value-fields, allowing dynamism in design, but loss for the strictly typing relational paradigm. Being a highly scalable open source distributed database to handle large amounts of data is a key component in cloud computing.

  • Cisco
  • Cloudkick
  • Digg
  • Facebook
  • Rack
  • Twitter

Cassandra’s largest group to date contains more than 400 machines.

Comments

“Cassandra Apache is a key component in the cloud computing and other applications that deal with large amounts of data and query high volumes,” said Jonathan Ellis, Vice President of Cassandra Apache. “It is particularly successful in feeding large websites with strong growth rates.” “Running any large website is a constant race between the scaling user base and scaling its infrastructure to support it,” said David King, lead developer at Reddit.
