DataStax Announces Community Edition 1.2 -- Latest Version of Apache Cassandra(TM) Includes Free Version of OpsCenter, the #1 Visual Management and Monitoring Solution for Cassandra

New Version Enables Greater Scalability and Reliability, Improves Developer Productivity and Simplifies Cluster Management; Community Edition 1.2 Features Virtual Nodes, CQL3 Improvements, Enhanced Request Tracing, Atomic Batches and Configurable Policies

SAN MATEO, CA -- (Marketwire) -- 01/10/13 -- DataStax, the company that powers the apps that transform business, today announced DataStax Community Edition 1.2, the latest version of Apache Cassandra™, the massively scalable open-source NoSQL database. The new release comes with a free edition of DataStax OpsCenter, the #1 visual management and monitoring solution in use today for Cassandra, which enables developers to manage and monitor their Cassandra clusters in point-and-click fashion from any location and from nearly any device.

DataStax Community Edition 1.2 contains all of Apache Cassandra 1.2's features including:

  • Virtual nodes, which improve the granularity of capacity increases, dramatically improve repair and rebuild times in larger clusters, and automatically keep the data in clusters balanced across all nodes

  • CQL3 improvements, notably the addition of collection types, query-able system information, and a CQL-native protocol

  • Request tracing allows developers and administrators to trace CQL requests on an individual or collective basis and easily understand what statements in a cluster are causing performance problems

  • Atomic batches ensure multiple statements sent to a cluster in batch are always applied in an all-or-nothing basis

  • Configurable policies for disk failure

DataStax Community Edition 1.2 also features many performance improvements to memory usage, column indexes, compaction, streaming, startup time and more.

"Cassandra 1.2 represents one of the most significant releases of the database yet," said Jonathan Ellis, chief technology officer, DataStax, and project chair of Apache Cassandra. "This new release makes it much easier for developers to insert and manipulate data, while CQL3 in 1.2 allows them to model data more naturally. We also worked to improve Cassandra deployments on denser hardware, with features like virtual nodes (vnodes), disk failure policies and compaction performance."

In addition to vnodes, the new release features atomic batches, inter-node communication and request tracing. These enhancements simplify the process of setting up new clusters and enable a higher level of cluster performance. CQL3, the third version of the Cassandra Query Language, is also being released with Cassandra 1.2. Developers can enjoy simplified application modeling, more powerful mapping and a more natural representation of data that diminishes design limitations, augmenting Cassandra's renowned scalability and reliability.

"C* 1.2 is huge, but it's hard to really put a finger on an overall theme because the improvements are so wide ranging," said Rick Branson, software engineer, Instagram. "The solidification of CQL3 and addition of atomic batches make huge leaps forward in terms of developer productivity. On the operations side, the addition of vnodes and off-heap internals (compression metadata & bloom filters) make managing a cluster much simpler and more hands-off."

"There is something in Apache Cassandra 1.2 for everybody," said Aaron Morton, independent Apache Cassandra committer. "Virtual Nodes and CQL 3 will make it easier for new users to set up a cluster and get productive. Existing users will see their clusters doing more thanks to the performance improvements, while everyone will benefit from the insights that request tracing brings."

"Virtual nodes are the most exciting feature for us," said Christos Kalantzis, engineering manager of cloud persistence engineering, Netflix. "The fact that we can autoscale our Cassandra clusters up and down on EC2 has already made a huge impact on our productivity."

Starting January 11, 2013, users can download DataStax Community Edition 1.2 by visiting

We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...

Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
Container technology is shaping the future of DevOps and it’s also changing the way organizations think about application development.

I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
Cloud computing delivers on-demand resources that provide businesses with flexibility and cost-savings. The challenge in moving workloads to the cloud has been the cost and complexity of ensuring the initial and ongoing security and regulatory (PCI, HIPAA, FFIEC) compliance across private and public clouds. Manual security compliance is slow, prone to human error, and represents over 50% of the cost of managing cloud applications. Determining how to automate cloud security compliance is critical to maintaining positive ROI. Raxak Protect is an automated security compliance SaaS platform and ma...
The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
