Sheetal Dolas is a Principal Architect at Hortonworks. As part of Apache Storm design patterns’ series blog, he explores three options for micro-batching using Apache Storm’s core APIs. This is the first blog in the series.

What is Micro-batching?

Micro-batching is a technique that allows a process or task to treat a stream as a sequence of small batches or chunks of data. For incoming streams, the events can be packaged into small batches and delivered to a batch system for processing [1]

Micro-batching in Apache Storm

In Apache Storm, micro-batching in core Storm topologies makes sense for performance or for integration with external systems (like ElasticSearch, Solr, HBase or a database).…

The key to monetization of Big Data is not only the ability to capture and process information quickly but also to analyze the data to derive meaningful insights.  Big Data can be complex, and often the expertise of a programmer is needed to create focused and targeted queries.

0xdata, a provider of open source machine learning and predictive analytics for Big Data, helps to facilitate the manipulation and extraction of data with the use of its H2O prediction engine for statisticians. …

A transformation is occurring in the data center.  Enterprises are turning to a modern data architecture in order to derive maximum value from both big and small data across their organization.  They are building new analytic apps that unlock opportunity and allow them to maintain or create competitive edge. Apache Hadoop is at the center of this architecture and integrates with the technologies that run your business to augment and extend this new value.…

Last week, Apache Tez graduated to become a top level project within the Apache Software Foundation (ASF). This represents a major step forward for the project and is representative of its momentum that has been built by a broad community of developers from not only Hortonworks but Cloudera, Facebook, LinkedIn, Microsoft, NASA JPL, Twitter, and Yahoo as well.

What is Apache Tez and why is it useful?

Apache™ Tez is an extensible framework for building YARN based, high performance batch and interactive data processing applications in Hadoop that need to handle TB to PB scale datasets.…

The Apache Pig community released Pig 0.13. earlier this month. Pig uses a simple scripting language to perform complex transformations on data stored in Apache Hadoop. The Pig community has been working diligently to prepare Pig to take advantage of the DAG processing capabilities in Apache Tez. We also improved usability and performance.

This blog post summarizes the progress we’ve made.

Support for Backends Other Than MapReduce

We made the Pig 0.13 architecture more general to support multiple backends beyond just MapReduce, while maintaining backward compatibility.…

As part of our YARN Ready program, we are hosting a series of technical webinars highlighting the technologies and resources available to developers for creating YARN applications. In our first webinar, “Introduction to YARN Ready,” we presented an overview of the YARN Ready program.

To extend your technical knowledge, please join us for our first in-depth YARN Ready technology webinar, “Integrating Applications Natively to YARN” on Thursday July 24 at 9am Pacific Time.…

Tresata, a Hortonworks Certified Technology Partner, is a next-generation predictive analytics software company that helps enterprises monetize big data™they have moved to Hadoop . In this blog, Tresata’s Director of Marketing, Katie Levans, (@katie_levans) describes the value of HDP 2.1 certification and the benefit of their solution.

Today we are delighted to announce the formal partnership between Accenture and Hortonworks, which is the continuing evolution of the ongoing collaboration between the two companies which started in 2012. With this formal agreement, Accenture and Hortonworks will collaborate on making large structured and unstructured datasets – including operational, video and sensor data – more accessible to organizations for insight-driven decision-making. Together, the two companies will continue to collaborate on joint horizontal and vertical solutions to speed the adoption of Apache Hadoop.…

Apache Cassandra is an open source NoSQL distributed database management system designed to handle large amounts of data offering a scalable real time solution that allows users to create online applications that are “always-on, no matter what.” DataStax is the company behind Cassandra, and a new Technology Partner of Hortonworks.

Lynn Walitch leads Partner Management for DataStax and is our guest blogger today. Lynn discusses the importance of the partnership and certification with Hortonworks.…

The Apache Storm community recently announced the release of Apache Storm 0.9.2, which includes improvements to Storm’s user interface and an overhaul of its netty-based transport.

We thank all who have contributed to Storm – whether through direct code contributions, documentation, bug reports, or helping other users on the mailing lists. Together, we resolved 112 JIRA issues.

Here are summaries of this version’s important fixes and improvements.

New Feature Highlights Netty Transport Overhaul

Storm’s Netty-based transport has been overhauled to significantly improve performance through better utilization of thread, CPU, and network resources, particularly in cases where message sizes are small.…

We recently hosted the sixth of our seven Discover HDP 2.1 webinars, entitled Apache Storm for Stream Data Processing in Hadoop. Over 200 people attended the webinar and joined in the conversation.

Thanks to our presenters Justin Sears (Hortonworks’ Product Marketing Manager), Himanshu Bari (Hortonworks’ Senior Product Manager for Storm), and Taylor Goetz (Hortonworks’ Software Engineer and Apache Storm Committer) who presented the webinar. The speakers covered:

  • Why use Apache Storm?
Big Data In Healthcare

Electronic data is the heartbeat in a healthcare provider’s office. ZirMed is a Hortonworks customer and a leading provider of healthcare information management solutions. Healthcare providers, including physicians, hospitals and large health systems, use the company’s cloud-based revenue cycle management offerings to manage the complex process of billing and collecting revenue from patients and payers.

ZirMed’s Analytics solution aggregates healthcare data and makes it available to its customers, so they get a clearer view of their financial and operational performance.…

We recently hosted the fifth of our seven Discover HDP 2.1 webinars, entitled Apache Solr for Hadoop Search. Over 200 people attended the webinar, prompting an informative discourse.

The speakers outlined the Apache Solr overview and features, followed by a practical demo of how to process, index, search, and visualize server log data.

Thanks to our presenters Justin Sears (Hortonworks’ Product Marketing Manager), Rohit Bakhshi (Hortonworks’ senior product manager), and Paul Codding (Hortonworks’ Solution Engineer) who presented the webinar.…
