What's New in Apache Cassandra 1.1

Title: What’s New in Apache Cassandra 1.1

Description: Apache Cassandra™ is a NoSQL database management system that provides continuous availability for real-time, big data applications that require extreme performance without compromise. Cassandra’s fully distributed architecture is designed for single or multiple data centers, including the cloud. It simplifies operations and development by providing location transparency to the application – meaning developers don’t have to worry about where they read or write to the database.

In October 2011, version 1.0 of Cassandra was released. This was a milestone for both those developing the software and using it. While some cutting-edge enterprises already had been in production with Cassandra for years, other more conservative companies were waiting for the first “official” or general availability (GA) release of the database system.

Cassandra 1.0 brought not only a GA version number, but also much-anticipated enhancements such as data compression, a new compaction methodology, increased performance, and more. Since that time, the Cassandra development team has been rolling out routine maintenance releases to 1.0 and also has been busy with the development of Cassandra 1.1.

This paper provides a brief overview of the new additions found in Cassandra 1.1, and supplies a concise introduction to Cassandra for those unfamiliar with its features and benefits.
