Polling Inbound Endpoints
- Former user (Deleted)
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 |
