Apache Cassandra Released

Apache, an Open source software developer, has launched Apache Cassandra v0.7, their ‎second generation open source distributed database.‎

Apache Cassandra is being used by Cisco, Cloudkick, Digg, Facebook, Rackspace, and ‎Twitter. The largest Cassandra cluster had over 400 machines. Apache Cassandra is an ‎important cloud computing component in applications dealing with large amounts of data ‎at high query volumes. ‎

Secondary indexes, novel methods to query data enabled through node-local storage on ‎the client side application and capable of supporting up to two billion columns per row, ‎are some of the key features of Apache Cassandra. Cassandra v0.7 also provides online ‎automated schema changes as regulated from the client API enabling modifications ‎consistent with object definitions that do not require a cluster restart.‎

Facebook open sourced Apache Cassandra in 2008, by bringing together Dynamo and ‎Google. Recently Google also provided a new module for the Apache Web server that ‎could instantly deploy multiple optimizations in order to accelerate website loading ‎operations.
