The choice flow control routes messages based on evaluating expressions against message properties or payload. It provides conditional logic similar to if/then/else statements, directing messages to the first routing option whose configuration evaluates to true, or to a default option if none match. Configuring it requires determining the evaluation criteria, routing options, processing for each, and default routing.

1. Choice Flow Control Reference
The choice flow control dynamically routes
messages based on message payload or
properties. It adds conditional programming
to a flow, similar to an if/then/else code
block.

2. • A choice flow control uses expressions to
evaluate the content of a message, then it
routes the message to one of the routing
options within its scope (see image below). It
directs messages to the first routing option in
the scope that matches the routing
configurations (evaluates to true). If none of
expressions evaluate to true, the choice flow
control directs the message to the default
(else) route.

4. Configuring the Choice Flow Control
• To configure the choice flow control, you need to determine the
following message routing details:
• Content the choice flow router should evaluate to determine
routing
• Number of routing options with which to supply the choice flow
control
• What processing Mule should perform for each routing option
• Default routing option
