Storm is a complex event processor and distributed computation framework written predominantly in the Clojure programming language. Originally created by Backtype, the project was open sourced after being aquired by Twitter.^[1] It uses custom created "spouts" and "bolts" to define information sources and manipulations to allow batch, distributed processing of streaming data. The initial release was on September 17, 2011.^[2]

A storm application is designed as a topology of interfaces which create a "stream" of transformations. It provides similar functionality as aMapReduce job with the exception that it will theoretically run indefinitely until it is manually terminated.^[3]

Development

Storm is developed under the Eclipse Public License, making it available to most companies to use. Github is used for version control and issue tracking.
