Polling Inbound Endpoints

A polling inbound endpoint polls periodically for data and when data is available the data is injected to a given sequence. For example, the JMS inbound endpoint checks the JMS queue periodically for messages and when a message is available that message is injected to a specified sequence. Polling inbound endpoints support one way operations and are asynchronous.

Common polling inbound endpoint parameters

The following parameters are common to all polling inbound endpoints:

Parameter Name	Description	Required	Possible Values	Default Value
interval	The polling interval for the inbound endpoint to execute each cycle. This value is set in milliseconds.	No	A positive integer	-
coordination	This parameter only applicable in a cluster environment. In a cluster environment an inbound endpoint will only be executed in worker nodes. If set to `true` in a cluster setup, this will run the inbound only in a single worker node. Once the running worker is down the inbound starts on another available worker in the cluster.	No	true or false	true
