Rabbit Sender

Description

This unit is a Processor type unit.

This unit writes into a RabbitMQ queue.
The destination can be a queue or an exchange. In both cases, if no RabbitMQ queue exists, it will be created.

An event comes in through the in port. When the event contains a field with the message to be written, the message is sent.
Successful input events are emitted through the done port without modification.
If an error occurs, the input event is enriched with standard error fields and emitted through the error port.</li>
