Transaction

The transaction in storm is mainly used under a circumstance of high precision, such as counting the amount or quantity, or synchronizing the database.

The implementation of the transaction management in storm is not that friendly for users, even becoming more abstruse after wrapping within Trident.

In the next step of JStorm, we'll redesign the transaction model based on Meta 1 and Meta 3, so it would be more handy and elegant.
