Master Branch:

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, is used by many companies, and is a lot of fun to use!

The Rationale page explains what Storm is and why it was built. This presentation is also a good introduction to the project.

Storm has a website at storm.apache.org. Follow @stormprocessor on Twitter for updates on the project.

Documentation and tutorials can be found on the Storm website.

Developers and contributors should also take a look at our Developer documentation.

If you are using a pre-built binary distribution of Storm, then chances are you should send questions, comments, storm-related announcements, etc. to [email protected].

If you are building storm from source, developing new features, or otherwise hacking storm source code, then [email protected] is more appropriate.

All existing messages will remain archived there, and can be accessed/searched here.

New messages sent to [email protected] will either be rejected/bounced or replied to with a message to direct the email to the appropriate Apache-hosted group.

You can also come to the #storm-user room on freenode. You can usually find a Storm developer there to help you out.
