Apache Storm is a distributed, fault tolerant, and scalable platform for processing streaming data, supporting real-time analytics and machine learning.
On September 17, the Apache Software Foundation (ASF) voted to graduate Apache Storm to a top-level project (TLP). This represents a major step forward for the project and represents the momentum built by a broad community of developers from not only Hortonworks, but also Yahoo!, Alibaba, Twitter, Microsoft and many other companies.
YARN and Apache Storm: A Powerful Combination YARN changed the game for all data access engines in Apache Hadoop. As part of Hadoop 2, YARN took the resource management capabilities that were in MapReduce and packaged them for use by new engines. Now Apache Storm is one of those data-processing engines that can run alongside …
Apache Hadoop is de facto standard for Big Data storage and batch processing, while Tweeter Storm is quickly becoming a standard for large-scale event processing implementations. Unfortunately, up until recently, Storm and Hadoop required two physically different clusters for their implementation. Last week Yahoo! announced open sourcing Storm running on a Hadoop cluster.
Hadoop users were excited to see the real-time Hadoop analytics demonstration at the Strata Conference in Santa Clara. By streaming the #strataconf twitter hashtag directly into a cluster during the conference, MapR displayed two real-time tag clouds showing a word bubble with the most frequently used words in conference tweets and a user name cloud of top tweeters. Watching the information change proved mesmerizing for some.
At Yahoo!, Hadoop plays a central role in providing personalized experiences for our users and creating value for our advertisers. To serve Yahoo!’s emerging business needs, the Cloud Engineering Group is working on a next generation platform that enables the convergence of big-data and low-latency processing.
Twitter has open sourced a “streaming MapReduce” system called Summingbird that makes Hadoop and Storm play nicer together so applications that require both batch and stream processing can do their jobs with as little complexity as possible.
These significant differences mean different processing infrastructures. Nathan Marz described this well in his How to Beat the CAP Theorem post. The result is a system that uses complementary technologies: stream-based processing with Storm and batch processing with Hadoop.
Interestingly, HBase sits at a juncture between realtime and batch processing models. It offers aspects of batch processing; computation can be moved to the data via direct MapReduce support. It also supports realtime patterns with random access and fas
Storm is a distributed and fault-tolerant realtime computation system. Similar to how Hadoop provides a set of general primitives for doing batch processing, Storm provides a set of general primitives for doing realtime computation.
