Creating a Message Queue Listen Adaptor
The Message Queue Listen Adaptor allows a graph to listen to messages arriving in a message queue and process them. The Listen Adaptor continuously polls the queue for new messages. The poll interval can be specified in the adaptor.
In order to create a Message Queue Listen Adaptor, it is best practice, but not necessary, to create a Queue Connection.
- To create the Message Queue Listen Adaptor on any graph, click on the Add Listener to Graph button in the top right-hand side of the graph window. This will bring up the Listener Editor window.
- Choose the connection from the Adaptor Connection drop down menu
- Specify the Listen Interval in seconds
- Choose the target location for the output from the queue
