Storm is a distributed 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. Storm is simple, can be used with any programming language, and is a lot of fun to use!

The Rationale page on the wiki explains what Storm is and why it was built. The video and slides of Storm's launch presentation are also good introductions to the project.

Follow @stormprocessor on Twitter for updates on the project.


Documentation and tutorials can be found on the Storm wiki.
