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

Developing software for the Internet of Things (IoT) comes with its own set of challenges. Security, privacy, and unified standards are a few key issues. In addition, each IoT product is comprised of at least three separate application components: the software embedded in the device, the backend big-data service, and the mobile application for the end user's controls. Each component is developed by a different team, using different technologies and practices, and deployed to a different stack/target - this makes the integration of these separate pipelines and the coordination of software upd...

When it comes to IoT in the enterprise, namely the commercial building and hospitality markets, a benefit not getting the attention it deserves is energy efficiency, and IoT’s direct impact on a cleaner, greener environment when installed in smart buildings. Until now clean technology was offered piecemeal and led with point solutions that require significant systems integration to orchestrate and deploy. There didn't exist a 'top down' approach that can manage and monitor the way a Smart Building actually breathes - immediately flagging overheating in a closet or over cooling in unoccupied ho...

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud without worrying about any lock-in fears. In fact by having standard APIs for IaaS would help PaaS expl...
Organizations already struggle with the simple collection of data resulting from the proliferation of IoT, lacking the right infrastructure to manage it. They can't only rely on the cloud to collect and utilize this data because many applications still require dedicated infrastructure for security, redundancy, performance, etc. In his session at 17th Cloud Expo, Emil Sayegh, CEO of Codero Hosting, will discuss how in order to resolve the inherent issues, companies need to combine dedicated and cloud solutions through hybrid hosting – a sustainable solution for the data required to manage I...

Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...
