A Route is a rule defining how messages will be moved from one service (or endpoint) to another. It is a graphical design, of two or more components connected together, that allows you to easily set up and test routing and mediation rules.
This feature is not shipped with your Talend Studio by default. You need to install it using the Feature Manager. For more information, see Installing features using the Feature Manager.
The Routes you design can address all of the different sources and targets that you need for your routing processes.
When you design a Route in Talend Studio, you can:
put in place routing or mediation rules using a library of technical components based on the standard Enterprise Integration Patterns.
change the default setting of components or create new components or family of components to match your exact needs.
create and add items to the repository for reuse and sharing purposes (in other projects or Routes or with other users).
