The Apache Software Foundation Announces Apache™ Cassandra™ v2.1
The Apache Software Foundation Announces the 5th Anniversary of Apache™ Cassandra™
Forest Hill, MD –08 April 2014– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 170 Open Source projects and initiatives, announced today the 5th Anniversary of Apache™ Cassandra™, the highly-performant Big Data distributed database.
"I am so proud to see what the Apache Cassandra community has been able to achieve in five short years," said Jonathan Ellis, Vice President of Apache Cassandra and DataStax CTO. "We've come such a long way since the early days, and it is a testament to Cassandra's rapid maturation that it has been deployed in over 1,500 global critical production environments."
Apache Cassandra is an Open Source, "NoSQL" distributed database management system designed to handle large amounts of data across many commodity servers quickly and reliably without compromising performance, whether running in the Cloud or in a hybrid data store. Cassandra offers robust support for clusters spanning multiple datacenters, and provides high availability with no single point of failure.
Originally developed at Facebook in 2008 to power their Inbox Search feature, Cassandra entered the Apache Incubator in 2009 and graduated as an Apache Top-level Project in February 2010.
Apache Cassandra has consistently led the NoSQL market in performance: its fully-distributed architecture provides unparalleled fault tolerance to ensure applications will not go offline, and its linear scalability allows them to reach massive sizes while successfully handling thousands of requests per second.
Cassandra Evolution 5 Years On: Under the Hood
Improved Performance in Real-world Situations
Apache Cassandra is used by many highly-visible organizations including: Adobe, Comcast, Disney, eBay, Eventbrite, GE, GoDaddy, HP, IBM, Instagram, Intuit, Netflix, Pearson, Safeway, Sky, Sony, Spotify, Travelocity, The Weather Channel, and Zoosk, among others. Additional organizations using Apache Cassandra can be found at http://planetcassandra.org/companies/
"We knew Apache Cassandra could perform linear scaling of reads and writes with consistent performance."
"Before adopting Cassandra, we could not monitor every malicious site and IP forever – the data volumes were just too great. No other database was ready for what we needed to do."
"Apache Cassandra provides us with an easy to use backend and lets us focus on our implementation and features."
"Apache Cassandra is critical for being able to look up historical behavior data quickly, so that we can do these model updates with low latency."
"Apache Cassandra provides us an easy way of providing a highly available store and not have to worry about things like sharding, multi-datacenter support and things like that. Cassandra is an amazing store. Some of the features that you get out of the box are pretty incredible. I think one of the reasons why Cassandra has taken off and is doing so well is because of its awesome community."
"Apache Cassandra embodies in its core the resilience and availability we need to continue serving our enterprise and internal customers even in the face of transient outages. Most of the time we forget about Cassandra and it keeps on running."
--Michael Rose, Senior Platform Engineer, FullContact
"The Google Cloud Platform was able to sustain one million Cassandra writes per second at a cost of $0.05 USD per million writes."
--Ivan Santa Maria Filho, Performance Engineering Lead, Google Cloud Performance Team
"We’re helping the world save water, which is a very laudable target for an innovative and commercial business. We’re using quite a lot of innovative technology to help us do that, of which Cassandra plays a major role."
"At Instagram we've either replaced or are replacing every use case of Redis with Apache Cassandra. Its operational robustness and ability to exploit solid-state disks are the primary drivers for these efforts. We've also used Cassandra as part of major new feature efforts for its ability to scale up, scale down, and transparently work in a multi-region environment."
"The data was stored originally in Oracle in such a way that it does not scale at all … We chose Cassandra because of its ability to scale easily, the operational simplicity, but also because it met our requirements."
"We absolutely love the data model and scalability that Cassandra offers us. Coupled with ease of use and the ability to get it up and running quickly in development means that we can experiment quickly and have code flow from development into production in a short amount of time."
"During Hurricane Sandy, we lost an entire data center. Completely. Lost. It. Our application fail-over resulted in us losing just a few moments of serving requests for a particular region of the country, but our data in Cassandra never went offline."
"Portugal Telecom is now expanding to Brazil, which is a market that is roughly 25 times larger than ours, so we believe with the help of Cassandra we’ll store huge loads of information."
"We are the number one source for weather on all platforms: TV, web, mobile, and API. Our digital group provides backend services across all our platforms —billions of requests per day— and is responsible for delivering scheduled and severe weather alerts. We make extensive use of Cassandra under the hood for our high-throughput use cases, and we support nearly every imaginable type of content. We get about 100M transactions per day on average against our busiest Cassandra-backed service, with a heavy day seeing more like 180-200M transactions. Apache Cassandra has never failed us."

The Apache Software Foundation Announces Apache™ Cassandra™ v2.0
Highly-performant, Open Source Big Data distributed database in use at Adobe, CERN, Comcast, eBay, GoDaddy, HP, IBM, Instagram, Netflix, Plaxo, and Sony, among others, to create modern, data-driven applications
Forest Hill, MD –4 September 2013– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives, today announced Apache Cassandra v2.0, the latest version of the highly-scalable, Big Data distributed database.
Apache Cassandra powers massive data sets quickly and reliably without compromising performance, whether running in the Cloud or partially on-premise in a hybrid data store. Its fully distributed architecture provides unparalleled fault tolerance to ensure applications will not go offline, and its linear scalability allows them to reach massive sizes while successfully handling thousands of requests per second.
"In five years, Apache Cassandra has grown into one of the most widely used NoSQL databases in the world and serves as the backbone for some of today’s most popular applications," said Jonathan Ellis, Vice President of Apache Cassandra.
Under the Hood
New features in Apache Cassandra v2.0 include lightweight transactions, triggers, and CQL (Cassandra Query Language) enhancements that increase productivity in creating modern, data-driven applications.
"Cassandra 2.0 makes it easier than ever for developers to migrate from relational databases and become productive quickly," added Ellis.
New features and improvements include:
- Lightweight transactions allow ensuring operation linearizability similar to the serializable isolation level offered by relational databases, which prevents conflicts during concurrent requests
- Triggers, which enable pushing performance-critical code close to the data it deals with, and simplify integration with event-driven frameworks like Storm
- CQL enhancements such as cursors and improved index support
- Improved compaction, keeping read performance from deteriorating under heavy write load
- Eager retries to avoid query timeouts by sending redundant requests to other replicas if too much time elapses on the original request
- Custom Thrift server implementation based on LMAX Disruptor that achieves lower message processing latencies and better throughput with flexible buffer allocation strategies
The Apache Cassandra developer community includes some of the brightest minds in Big Data. Hundreds of organizations, from startups to large-scale enterprises such as Adobe, Cisco and IBM, rely on Cassandra to power their mission-critical applications online.
"At Ooyala, we're building some of our most ambitious projects to date on top of Apache Cassandra," said Al Tobey, Tech Lead, Compute and Data Services, Ooyala. "The maturation of CQL3, vnodes, and new features such as the PAXOS-backed compare-and-set (CAS) added in Cassandra 2.0 will help us build and deploy those projects confidently."
Apache Cassandra is used by many highly-visible organizations such as Accenture, CERN, Cloudkick, Comcast, Constant Contact, Dell, Digg, Ericsson, Eventbrite, GoDaddy, Houghton Mifflin Harcourt, HP, Instagram, Intuit, Mahalo, Microsoft MetricsHub, Morningstar, NASA, Netflix, Nextag, OpenWave, PBS Kids, Pitney Bowes, Plaxo, Polyvore, Real Networks, Reddit, Sony Network Entertainment, SoundCloud, Spotify, Squidoo, Stormpath, Symantec, Twitter, Wildfire, WSO2, and ZoomInfo. A listing of where Apache Cassandra is used and deployment details can be found at http://planetcassandra.org/Company/ViewCompany?IndustryId=-1
"We are excited about the future Apache Cassandra 2.0 makes possible. Paying down a lot of the technical debt accumulated over 5 years of intense Open Source development, and solidifying the Native Binary Transport for CQL 3, has put the project on a great footing," said Aaron Morton, Apache Cassandra committer and Co-Founder & Principal Consultant of The Last Pickle. "The addition of Lightweight 'Compare-and-Set' Transactions and Cursors brings another set of features that make it easier for developers to harness the performance and scale of Cassandra. And the experimental Trigger support will allow Open Source contributors to provide feedback for this often requested feature."
"It'll be really helpful to have conditional updates built into Cassandra," explained Jon Haddad, Senior Architect at Shift. "Right now there's a few places where we have to use external locking to manage isolation, and having built in support in the database will be amazing."
"We feel this release will delight existing users and tempt those on the sidelines," added Morton.
As with all Apache products, Apache Cassandra v2.0 is released under the Apache License v2.0, and is overseen by a self-selected team of active contributors to the project. A Project Management Committee (PMC) guides the Project's day-to-day operations, including community development and product releases. Apache Cassandra source code, documentation, and related resources are available at http://cassandra.apache.org/.

The Apache Software Foundation Announces New Top-Level Projects
Record Number of Projects Launched via Apache Incubator and Current Initiatives
FOREST HILL, MD – 4 May, 2010 – The Apache Software Foundation (ASF) –-the all-volunteer developers, stewards, and incubators of 143 Open Source projects and initiatives-- today announced the creation of six new Top-Level Projects (TLPs), setting an all-time record of the most new TLPs launched in a single month.
A Top-Level Project signifies that a Project's community and products have been well-governed under the ASF's meritocratic, consensus-driven process and principles. Whilst a project is developing within the Apache Incubator or as a sub-project of an existing TLP, it benefits from hands-on mentoring from other Apache contributors, as well as the Foundation’s widely-emulated process, stewardship, outreach, support, and community events.
"Becoming a Top-Level Project is a vote of confidence from the Foundation at-large, demonstrating a project has proven its ability to be properly self-governed," said ASF Chairman Jim Jagielski. "We are proud of our Committers' dedication in building robust communities under the ASF process known as 'The Apache Way'."
All Apache Projects are overseen by a self-selected team of active contributors to the project. Upon a Project's maturity to a TLP, a Project Mangement Committee (PMC) is formed to oversee its day-to-day operations, including community development and product releases.
The six new TLPs include both a graduating project from the Apache Incubator as well as sub-projects of existing TLPs. They are:
Graduating from the Apache Incubator
Former Sub-projects of Existing Top-Level Projects
- Apache Mahout provides scalable implementations of machine learning algorithms on top of Apache Hadoop and other technologies. It offers collaborative filtering, clustering, classification, feature reduction, data mining algorithms, and more. Begun as a sub-project of Lucene in 2008, Mahout's team of nearly a dozen contributors is now actively working towards release 0.4.
- Apache Tika is an embeddable, lightweight toolkit for content detection, and analysis. Powering by MIME standards from IANA, advanced language detection features and on the ability to rapidly unify existing parser libraries, Tika provides a one-stop shop for navigating the modern information landscape. Tika entered the Incubator in 2007 and graduated to a Lucene sub-project in 2008. Tika is used in a broad range of Lucene products ranging from Solr, to Nutch and Mahout and is in deployment at NASA, Day Software, the Internet Archive, and at a number of Web startups including Bixo labs.
- Apache Nutch is a highly-modular, Web searching engine based on Lucene Java with added Web-specifics, such as a crawler, a link-graph database, and parsers for HTML and other document formats. Its architecture allows developers to create plugins for media-type parsing, data retrieval, querying, clustering, and more. Following a successful 100 million page demo system, the project graduated the Apache Incubator in 2005 to become a sub-project of Apache Lucene.
- Apache Avro is a fast data serialization system that includes rich and dynamic schemas in all its processing. A sub-project of Apache Hadoop, Avro features rich data structures; a compact, fast, binary data format; a container file to store persistent data; remote procedure call (RPC); and simple integration with dynamic languages. Not only is code generation not required to read or write data files nor to use or implement RPC protocols, it is an optional optimization, only worth implementing for statically typed languages.
- Apache HBase is a distributed database modeled after Google's Bigtable. The project started at Powerset and became a sub-project of Apache Hadoop in 2007. Apache HBase adds random read/write access to the Hadoop stack, extending offline processing capabilities and enabling realtime serving of very large datasets. The project's goal is the hosting of big tables -- billions of rows X millions of columns -- running atop commodity hardware. HBase has been successfully deployed at Adobe, Flurry, Meetup, Mozilla, StumbleUpon, Trend Micro, and Twitter, among others, to perform analytics and as a datastore for live Websites.
Additional New Top-Level Projects Created in 2010
- Apache UIMA (Unstructured Information Management Architecture) is a framework for analyzing unstructured information, such as natural language text. It supports the writing, deployment and reuse of analysis components in a wide variety of settings. Created at IBM and submitted to the Apache Incubator in 2006, UIMA has been adopted as the de-facto enabling platform by a significant part of the natural language processing community. Apache UIMA graduated from the Apache Incubator in March 2010.
- Apache Cassandra is an advanced, second-generation “NoSQL” distributed data store that has a shared-nothing architecture. The Cassandra decentralized model provides massive scalability, and is highly available with no single point of failure even under the worst scenarios. Originally developed at Facebook and submitted to the ASF Incubator in 2009, the Project has added more than a half-dozen new committers, and is deployed by dozens of high-profile users such as Cisco WebEx, Cloudkick, Digg, Facebook, Rackspace, Reddit, and Twitter. Apache Cassandra graduated from the Apache Incubator in March 2010.
- Apache Subversion is a widely-used versioning control system. The project was initated at CollabNet in 2000 and was accepted into the Apache Incubator in 2009; many of the people who founded Subversion also actively contribute to various initiatives at the ASF. All of the ASF's projects use Subversion for source code version control, and Subversion itself relies on many Apache projects such as Apache Portable Runtime (APR) and HTTP Web Server. For nearly a decade, both communities have benefited from open feedback channels, where requirements from the Subversion project have helped drive new features to various Apache projects, and vice versa. Apache Subversion is used in Bounty Source, CodePlex, Django, ExtJS, Free BSD, FreePascal, GCC, Google Code, MediaWiki, Mono, PHP, Ruby, SourceForge, and Tigris.org, as well as numerous corporations. Apache Subversion graduated from the Apache Incubator in February 2010.
- Apache Click is a modern Java EE Web application framework that provides a natural, rich client style programming model. Apache Click's intuitive design makes it very easy to learn and use, with most developers getting up and running within a day. As opposed to traditional component oriented Web frameworks, Click is stateless by design although stateful pages are supported. Click exposes few abstractions to learn and understand; the Java Servlet API is fully exposed to the developer to ease the upgrade path from an action-based framework to a component-based one to alleviate developers from maintaining redundant markup. Apache Click entered the Apache Incubator in 2008 and graduated in February 2010.
- Apache Shindig is an OpenSocial container and helps you to start hosting OpenSocial apps quickly by providing the code to render gadgets, proxy requests, and handle REST and RPC requests. By providing a language-neutral infrastructure for those wishing to host OpenSocial applications on their Websites, Apache Shindig allows new sites to start hosting social apps in under an hour. Originally created as a port of Google's iGoogle gadget container for hosting OpenSocial compatible widgets in any Website, Shindig entered the Apache Incubator in 2007, and graduated in January 2010.
"The ASF has been at the center of innovation over the past 10 years, providing key pieces for much of the software and services we rely on every day," said RedMonk analyst Michael Coté. "These new Top-Level Projects are another example of that in action: projects that aim to help developers and organizations build the next round of useful applications."
All Apache products are released under the Apache Software License v2.0. Downloads, documentation, and related resources are available at http://www.apache.org/.
About the Apache Incubator and Incubation Process
The Apache Incubator is the entry path for projects and codebases wishing to become part of the efforts at The Apache Software Foundation. All code donations from external organisations and existing external projects wishing to join the ASF enter through the Incubator to: 1) ensure all donations are in accordance with the ASF legal standards; and 2) develop new communities that adhere to our guiding principles. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
About The Apache Software Foundation (ASF)
Established in 1999, the all-volunteer Foundation oversees more than one hundred 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 2,300 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 Apache Software Foundation Announces Apache Cassandra Release 0.6
Newest version of leading Open Source, NoSQL distributed database management system now available.
FOREST HILL, MD – 13 April, 2010 – The Apache Software Foundation (ASF) --developers, stewards, and incubators of 138 Open Source projects-- today announced Apache Cassandra version 0.6, the Project's latest release first since its graduation from the ASF Incubator in February 2010.
Apache Cassandra is an advanced, second-generation “NoSQL” distributed data store that has a shared-nothing architecture. The Cassandra decentralized model provides massive scalability, and is highly available with no single point of failure even under the worst scenarios.
"In response to the growing need for scalable, high-throughput databases, we are pleased to release Cassandra 0.6," said Jonathan Ellis, Apache Cassandra Project Management Committee Chair. "It's fantastic seeing the Project's community at the ASF grow to match the promise of the technology."
Originally developed at Facebook and submitted to the ASF Incubator in 2009, the Project has added more than a half-dozen new committers, and is deployed by dozens of high-profile users such as Cisco WebEx, Cloudkick, Digg, Facebook, Rackspace, Reddit, and Twitter, among others.
"The services we provide to customers are only as good the systems they are built on," said Eric Evans, Apache Cassandra committer and Systems Architect at The Rackspace Cloud. "With Cassandra, we get the fault-tolerance and availability our customers demand, and the scalability we need to make things work."
Cassandra 0.6 features include:
- Support for Apache Hadoop: this allows running analytics queries with the leading map/reduce framework against data in Cassandra.
"Digg is very excited to see Cassandra mature in the last year and graduate to a top-level Apache project. Cassandra is powering our next generation infrastructure, and allowing us to run in an environment that demands data access in datacenters around the world," said Chris Goffinet, Performance and Availability Architect at social news website Digg.
- Integrated row cache: this eliminates the need for a separate caching layer, thereby simplifying architectures.
Powering more than 10 billion pages, Twitter switched to Apache Cassandra because it can run on large server clusters and is capable of taking in very large amounts of data at a time. Storage Team Technical Lead Ryan King explained, "At Twitter, we're deploying Cassandra to tackle scalability, flexibility and operability issues in a way that's more highly available and cost effective than our current systems."
- Increased speed: this builds on Cassandra's highly-launded ability to process thousands of writes per second, allowing solutions of all kinds to cope with increasing write loads.
"Apache Cassandra 0.6 is 30% faster across the board, building on our already-impressive speed," added Ellis. "It achieves scale-out without making the kind of design compromises that result in operations teams getting paged at 2 AM."
Released under the Apache Software License v2.0, Apache Cassandra 0.6 can be downloaded at http://cassandra.apache.org/.
