JStorm is an implementation of Storm in java.

Why we develop JStorm?

Storm is a wonderful product, but it is developed in Clojure,which is not a popular language. And in our company, few guys can fix the bug of Storm, which we already found in zeromq, zookeeper, performance,etc.
So, we decided to implement JStorm.

What's the status of JStorm?

Alipay began to use JStorm in May 2013.Till Sep 2013, JStorm in Alipay can handle
40TB/3billion messages from other clusters . In some topologies, no message misses.

What is the difference between JStorm and Storm?
