Highly-scalable Open Source Distributed Database for Handling Large Amounts of 
Data is a Key Component in Cloud Computing

Forest Hill, MD – 11 January 2011 – The Apache Software Foundation (ASF), the 
all-volunteer developers, stewards, and incubators of nearly 150 Open Source 
projects and initiatives, today announced Apache Cassandra v0.7, the 
highly-scalable, second generation Open Source distributed database.

"Apache Cassandra is a key component in cloud computing and other applications 
that deal with massive amounts of data and high query volumes," said Jonathan 
Ellis, Vice President of Apache Cassandra. "It is particularly successful in 
powering large web sites with sharp growth rates."

Apache Cassandra is successfully deployed at organizations with active data 
sets and large server clusters, including Cisco, Cloudkick, Digg, Facebook, 
Rackspace, and Twitter. The largest Cassandra cluster to date contains over 400 
machines.

"Running any large website is a constant race between scaling your user base 
and scaling your infrastructure to support it," said David King, Lead Developer 
at Reddit. "Our traffic more than tripled this year, and the transparent 
scalability afforded to us by Apache Cassandra is in large part what allowed us 
to do it on our limited resources. Cassandra v0.7 represents the real-life 
operations lessons learned from installations like ours and provides further 
features like column expiration that allow us to scale even more of our 
infrastructure."

Among the new features in Apache Cassandra v0.7 are:

- Secondary Indexes, an expressive, efficient way to query data through 
node-local storage on the client side;

- Large Row Support, up to two billion columns per row;

- Online Schema Changes – automated online schema changes from the client API 
allow adding and modifying object definitions without requiring a cluster 
restart.

Oversight and Availability
Apache Cassandra is available under the Apache Software License v2.0, and is 
overseen by a Project Management Committee (PMC), who guide its day-to-day 
operations, including community development and product releases.

Apache Cassandra v0.7 downloads, documentation, and related resources are 
available at http://cassandra.apache.org/.

About The Apache Software Foundation (ASF)
Established in 1999, the all-volunteer Foundation oversees nearly one hundred 
fifty leading Open Source projects, including Apache HTTP Server — the world's 
most popular Web server software. Through the ASF's meritocratic process known 
as "The Apache Way," more than 300 individual Members and 2,500 Committers 
successfully collaborate to develop freely available enterprise-grade software, 
benefiting millions of users worldwide: thousands of software solutions are 
distributed under the Apache License; and the community actively participates 
in ASF mailing lists, mentoring initiatives, and ApacheCon, the Foundation's 
official user conference, trainings, and expo. The ASF is funded by individual 
donations and corporate sponsors including AMD, Basis Technology, Cloudera, 
Facebook, Google, IBM, HP, Matt Mullenweg, Microsoft, SpringSource, and Yahoo!.
