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™ Olingo™ as a Top-Level Project
Open Source, generic Java client and server library implementation of the OData (Open Data Protocol) standard for interoperable querying and sharing of data across applications in enterprise, Cloud, and mobile environments
Forest Hill, MD –07 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 that Apache™ Olingo™ has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the project's community and products have been well-governed under the ASF's meritocratic process and principles.
"We are pleased to graduate from the Apache Incubator," said Stephan Klevenz, Vice President of Apache Olingo. "The Apache Way of collaborative software development shows that it is possible to produce high-quality and faithful implementations of standards." Klevenz is also a development architect at SAP and an Apache committer since 2010.
Apache Olingo provides generic Java and JavaScript libraries that implement the Open Data Protocol (OData), the standardized data access protocol used for creating and consuming data APIs in an interoperable manner across applications and devices. OData provides a uniform way to expose full-featured data APIs by building on core protocols such as HTTP as well as commonly accepted methodologies such as REST.
Apache Olingo serves client and server aspects of OData 2.0, and will serve as a code base for OData 4.0, the OASIS standard of the protocol (OASIS OData TC). The OASIS international open standards consortium recently announced that Open Data Protocol (OData) version 4.0 and OData JavaScript Object Notation (JSON) Format version 4.0 have been approved as OASIS Standards. These REST-based standards simplify the querying, sharing, and consuming of data across applications for re-use in enterprise, Cloud, and mobile environments. More information on the OData ecosystem of open data producer and consumer services is available at http://www.OData.org/
Olingo is used by browser-based user interfaces to query data residing on servers. It is also used to synchronize data to mobile devices, and exchange data between server systems, and is part of the technical foundation of SAP NetWeaver® Gateway technology, among other enterprise solutions.
Apache Olingo supports multiple languages, including Java and JavaScript for OData clients and servers, namely OData 2.0 in Java, OData 4.0 in Java, and OData 4.0 in JavaScript. Olingo extensions contain additional features, such as the support of Java Persistence API (JPA) or annotated bean classes. The project's documentation, wiki, and tutorials highlight several examples of implementing a custom OData service, including a sample Web application built with Apache Maven that can be deployed to any Java Platform, Enterprise Edition (JEE)-compliant Web application server, such as Apache Tomcat.
"OData v4 recently became an OASIS standard that is increasingly opening up data for an open Web," said Eduard Koller, Senior Program Manager at Microsoft Open Technologies, Inc. "Apache Olingo is open source software to aid in the production of OData v4.0 clients and servers in both Java and JavaScript. The project brings together several companies and community developers and we look forward to welcoming more users and contributors to the community."
Availability and Oversight
As with all Apache products, Apache Olingo software 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.

The Apache Software Foundation Announces Apache™ Tajo™ as a Top-Level Project
Forest Hill, MD –01 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 that Apache Tajo has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the project's community and products have been well-governed under the ASF's meritocratic process and principles.
"It's a pleasure to graduate from the Apache Incubator," said Hyunsik Choi, Vice President of Apache Tajo. "This milestone further reinforces our hard work in bringing a much-needed big data solution under the Apache banner."
Dubbed an "SQL-on-Hadoop" solution, Apache Tajo is a robust big data relational and distributed data warehouse system for Apache Hadoop. Tajo is designed for low-latency and scalable ad-hoc queries, online aggregation, and ETL (extract-transform-load process) on large-data sets stored on HDFS (Hadoop Distributed File System) and other data sources. By supporting SQL standards and leveraging advanced database techniques, Tajo allows direct control of distributed execution and data flow across a variety of query evaluation strategies and optimization opportunities.
The Tajo project began in 2010 at Korea University's Database Lab, and entered the Apache Incubator in March 2013. Apache Tajo is in use at Gruter, Korea University, and SK Telecom, among others, for its ability to analyze massive data sets in real time.
"Apache Tajo has earned its place as a top-level project in the ASF. It's an excellent example of a community building around a core piece of technology. Not to mention, the technology itself is quite cool. Tajo has a large role to play in the Apache Hadoop ecosystem," said Jakob Homan, Staff Software Engineer at LinkedIn, and ASF Member.
"Tajo project is a really good example that how company and Open Source community can benefit from each other. Its real open community has assisted me to solve lots of practical problems, and I have opportunities to make Tajo more robust and have richer functionalities," said Keuntae Park, IT manager of SK Telecom and contributor to Apache Tajo. "I feel much affection for Tajo project and it's my great pleasure to participate in its growth, graduation, and becoming of top-level project."
"Tajo is one of the most promising projects for SQL-on-Hadoop. Many contributors have been improving Tajo by developing various interesting features. It's an honor for me to work with such a wonderful community," said Jihoon Son, Ph.D. candidate at Korea University and contributor to Apache Tajo.
"Apache Tajo has been a model community through the Incubator. They have demonstrated meritocracy on lists in the face of some pretty awesome and complex software for Big Data Analytics," said Chris Mattmann, Apache Tajo Incubator Mentor at the ASF, and Chief Architect, Instrument and Science Data Systems Section at NASA JPL. "We are currently evaluating the use of Tajo in projects for Radio Astronomy at JPL, as well as in the context of our Airborne Snow Observatory (ASO) project for Big Data query processing and storage. I'm really excited to see where Tajo is headed along with the other Big Data stacks at the ASF including Spark and Mesos."
"The key to a successful Open Source community lies in its diversity and active participation," added Choi. "As Apache Tajo continues to grow, we welcome contributions with code, documentation, testing, submitting patches, and other valuable forms of feedback."

The Apache Software Foundation Announces Apache™ Open Climate Workbench™ as a Top-Level Project
Open Source analysis and evaluation toolkit initiated by UCLA and NASA/JPL's Regional Climate Model Evaluation System (RCMES) scientific collaboration; used in regional weather research and global climate dynamics modeling
Forest Hill, MD –03 March 2014– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 170 Open Source projects and initiatives, announced today that the Apache Open Climate Workbench Project (a.k.a. "Apache Climate" or "Apache OCW") has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the project's community and products have been well-governed under the ASF's meritocratic process and principles.
Apache Climate is a climate evaluation toolkit used to leverage model outputs from organizations such as the Earth System Grid Federation (ESGF), the Coordinated Regional Downscaling Experiment (CORDEX), the U.S. National Climate Assessment (NCA), and the North American Regional Climate Change Assessment Program (NARCCAP), coupled with remote sensing data from the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and other agencies.
"Collaboration and science go hand in hand so it's great to see NASA, CORDEX, NARCCAP, universities from around the world, and the greater climate science community embracing Open Source and the ASF," said Michael Joyce, Vice President of Apache Climate. "The Open Climate Workbench has had an amazing journey with a great team of contributors and I'm excited to see where it's going."
Originally seeded from the Regional Climate Model Evaluation System (RCMES) code from the Joint Institute for Regional Earth System Science and Engineering (JIFRESSE) scientific collaboration between University of California at Los Angeles (UCLA) and the NASA Jet Propulsion Laboratory (JPL), the Apache Climate toolkit includes capabilities for data rebinning, metrics computation, and visualization. RCMES now relies extensively on Apache Climate; those members of the global climate community who have been using RCMES prior to its submission to the Apache Incubator in February 2013 have advanced to using RCMES powered by Apache Open Climate Workbench.
Apache Climate features prominently in research applications, with the system used to analyze recent developments in United States and Africa, as well as examine the uncertainty in observed precipitation datasets over the India-Tibet region.
"The Indian Institute of Tropical Meteorology are the main the regional climate institution in India related with climate change and impact assessments for India and surrounding regions," explained Jinwon Kim, regional climate modeling lead scientist at JIFRESSE and researcher at the UCLA Department of Atmospheric and Oceanic Sciences.
"I am using components of Apache OCW in my research to build an application that can identify weather-scaled phenomenon in long-term high resolution satellite (and eventually climate model) datasets," said Kim Whitehall, PhD student in the Howard University Program in Atmospheric Sciences (HUPAS).
Apache Climate is the result of an estimated 24 years of effort (as calculated by the COCOMO – Constructive Cost Model), with nearly 850 commits by 15 individual contributors (representing 94,843 lines of code) during its first year at The Apache Software Foundation.
To manage the massive datasets associated with the metrics, visualizations, and algorithms that support RCMES, Apache Climate is often paired with Apache OODT™ (Object Oriented Data Technology), the Open Source data management system framework originally developed at NASA for information integration and for science data processing and retrieval.
"Leveraging Apache OODT, which was reused on SNPP (Suomi National Polar-Orbiting Partnership) and JPSS (Joint Polar Satellite System) satellite missions, and the Apache open source governance, the OCW is the next step in the development of an integrated climate community research and development environment," explained Dr. Tsengdar Lee, Scientific Computing Portfolio Manager and Weather Data Analysis Program Scientist at the NASA Science Mission Directorate. "It will be developed by the community for the community in a completely open way."
"The community is always looking for good tools to analysis massive amounts of distributed data. It looks like Apache Climate can help in that effort," said Dean Williams, Analytics and Informatics Management Systems project leader at the Lawrence Livermore National Laboratory (LLNL) and Principal Investigator of the Earth System Grid Federation.
A demonstration of RCMES powered by Apache Climate is available at http://rcmes.jpl.nasa.gov/training/videos

Forest Hill, MD –27 February 2014– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 170 Open Source projects and initiatives, announced today that Apache Spark has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the project's community and products have been well-governed under the ASF's meritocratic process and principles.
"It's great to see Apache become Spark’s permanent home," said Matei Zaharia, Vice President of Apache Spark. "Spark has quickly become one of the most active projects in the Hadoop ecosystem, with dozens of organizations contributing, and we look forward to working closely with the rest of the Apache community."
"This is a major milestone for the students and researchers in the AMPLab," said Mike Franklin, Director of the AMPLab at UC Berkeley. "Spark demonstrates the real impact that research can have and validates the support AMPLab has received from our White House-announced NSF Expeditions in Computing Award and our 20+ industrial sponsors and collaborators."
"Through our work on Spark at both AMPLab and Databricks, we’ve focused on making it much easier for organizations to get insights from big data," said Ion Stoica, CEO at Databricks and Professor at UC Berkeley. "We're doing this together with a fantastic open source community. We look forward to continue working with the community to accelerate the development and adoption of Apache Spark."
Since entering the Apache Incubator in June 2013, Apache Spark bolstered its community through code contributions by more than 120 developers from 25 organizations. Apache Spark is in use at an array of global corporations that include Alibaba, Cloudera, Databricks, IBM, Intel, and Yahoo, among others.
"I'm really proud of the community aspect that has become infectious in Apache Spark and that really grew out of the energy in the project starting in the AMP Lab and through its movement to the ASF," said Chris Mattmann, Apache Spark Incubator Mentor at the ASF, and Chief Architect, Instrument and Science Data Systems Section at NASA JPL. "Matei, Patrick, Reynold, and many of the leaders of the project have really done a tremendous job and I'm excited to see the next generation of Hadoop-style systems have a home at the ASF."

The ASF asks: Have you met Apache™ Marmotta™?
Quick peek: Apache Marmotta is an Open Platform for Linked Data, a paradigm promoted by the World Wide Web Consortium (W3C) for large scale data integration across the Web based the RDF technology stack.
Background: Initiated in 2008 by a group of researchers from Salzburg Research as the EU-funded KiWi project (investigated the idea of "Semantic Wikis" and aimed at combining easily editable Web content with Semantic Web technologies to provide data to both human and machine users), later refocused and renamed as LMF. The project was contributed as "Marmotta" to the Apache Incubator in December of 2012. Apache Marmotta graduated as an Apache Top-Level Project in November 2013.
Why Marmotta: Apache Marmotta was created to provide an Open Source implementation of Linked Data technologies in general, and Linked Data Platform in particular. Usually organizations who want to use this technology need to assemble together different pieces of software, with the obvious problems derived, both technical and legal. Apache Marmotta satisfies that need of the industry, supporting almost any use-case with a permissive Open Source license.
Apache Marmotta powers Salzburger Nachrichten's search and archive, the Open Data portal at Enel, as well as Redlink's cloud infrastructure, among other implementations.
- The Marmotta Platform, a JavaEE web application providing the Linked Data server;
- KiWi, a Sesame-based triple store built on top of a relational database, including reasoning and versioning;
- LDPath, a path language to navigate across Linked Data resources;
- LDClient, a client that allows retrieval of remote legacy resources not available as Linked Data; and
- LDCache, a cache system that automatically retrieves resources by internally using LDClient

The Apache Software Foundation Announces Apache™ Hadoop™ 2
Forest Hill, MD –16 October 2013– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives, today announced Apache™ Hadoop™ 2, the latest version of the Open Source software framework for reliable, scalable, distributed computing.
A foundation of Cloud computing and at the epicenter of "big data" solutions, Apache Hadoop enables data-intensive distributed applications to work with thousands of nodes and exabytes of data. Hadoop enables organizations to more efficiently and cost-effectively store, process, manage and analyze the growing volumes of data being created and collected every day. Apache Hadoop connects thousands of servers to process and analyze data at supercomputing speed.
"Hadoop 2 marks a major evolution of the open source project that has been built collectively by passionate and dedicated developers and committers in the Apache community who are committed to bringing greater usability and stability to the data platform," said Arun C. Murthy, release manager of Apache Hadoop 2 and Founder of Hortonworks Inc. "It has been an honor and pleasure to work with the community and a personal thrill to see our four years of work on YARN finally coming to fruition in the GA of Hadoop 2. Hadoop is truly becoming a cornerstone of the modern data architecture by enabling organizations to leverage the value of all their data, including capturing net-new data types, to drive innovative new services and applications."
"What started out a few years ago as a scalable batch processing system for Java programmers has now emerged as the kernel of the operating system for big data," said original Hadoop creator and ASF Board member Doug Cutting. "Over a dozen Apache projects integrate with Hadoop, with ten more in the Apache Incubator poised to soon join their ranks."
Under the Hood
New in Hadoop 2 is the addition of YARN that sits on top of HDFS and serves as a large-scale, distributed operating system for big data applications, enabling multiple applications to run simultaneously for more efficient support of data throughout its entire lifecycle. The culmination of so many other releases in the Hadoop 2.x line, the most current release --2.2.0-- is the first stable release in the 2.x line. Features include support support for:
- Apache Hadoop YARN, a cornerstone of next generation Apache Hadoop, for running both data-processing applications (e.g. Apache Hadoop MapReduce, Apache Storm etc.) and services (e.g. Apache HBase)
- High Availability for Apache Hadoop HDFS
- Federation for Apache Hadoop HDFS for significant scale compared to Apache Hadoop 1.x.
- Binary Compatibility for existing Apache Hadoop MapReduce applications built for Apache Hadoop 1.x.
- Support for Microsoft Windows.
- Snapshots for data in Apache Hadoop HDFS.
- NFS-v3 Access for Apache Hadoop HDFS.
"The community has stepped up to the challenge of making Hadoop enterprise-ready, hardening the filesystem, providing high availability, adding critical security capabilities,and delivering integrations to enable consolidation of any kind or amount of enterprise data," said Aaron Myers, member of the Apache Hadoop Project Management Committee and Engineer at Cloudera.
"Today, with the announcement of Hadoop 2 and YARN, we've taken another step. Beyond the basic multitenancy customers have enjoyed for the past year, enabling them to mix batch, interactive and real-time workloads, they now have the ability to do so from within a stable foundational part of the Hadoop ecosystem. It's a testament to the community's work that now every distribution of Apache Hadoop will enjoy these benefits, ensuring that customers can deliver the applications they need, on a single Hadoop platform."
"It has been an honor and pleasure to work with the community and a personal thrill to see our four years of work on YARN finally coming to fruition in the GA of Hadoop 2," added Murthy. "Apache Hadoop is truly becoming a cornerstone of the modern data architecture by enabling organizations to leverage the value of all their data, including capturing net-new data types, to drive innovative new services and applications."
"A large portion of the credit for this success is due to Apache's open-source model, which has permitted a wide range of users and vendors to productively collaborate on a platform shared by all," added Cutting.
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 400 individual Members and 3,500 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 a US 501(c)(3) charitable organization, funded by individual donations and corporate sponsors including AMD, Basis Technology, Budget Direct, Citrix, Cloudera, Comcast, Facebook, Go Daddy, Google, HP, Hortonworks, Huawei, IBM, InMotion Hosting, Matt Mullenweg, Microsoft, PSW Group, Pivotal, WANdisco, and Yahoo!.

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.
Availability and
