You open the Kafka forwarding agent configuration dialog from a workflow configuration: you can right-click the agent icon and select Configuration..., or double-click the agent icon. The agent configuration has two tabs; Forward and Override. The settings in the Override tab is only relevant when you are using Kafka client 0.8.
The Forward Tab
The Forward tab contains the general configuration for the Kafka forwarding agent.
Kafka forwarding agent configuration - Forward tab
| Setting | Description |
|---|---|
Profile | The name of the profile as defined in the Kafka Profile Editor (select Kafka Profile after clicking the New Configuration button in the Desktop). |
| Standard | Select this option if you do not require acknowledgments to be sent to an external system. |
| Acknowledged | Select this option to enable an acknowledgement to be sent back to an external system. Acknowledged execution mode consumes more resources since every outstanding request contains data from a response UDR. |
Route On Error | Select this check box if you want a Note! The emission of error UDRs is under flood protection, which means only one unique error message UDR is issued per second to prevent flooding of identical errors. In addition, if you set the number of retries to a value greater than 0 in the Advanced tab of the Producer tab in the Kafka Profile configuration dialog, the error message UDR is not emitted until the final retry has failed. |
| Suppress non-fatal errors | Select this check box if you do not want to log non-fatal errors produced by the Kafka forwarding agent in the System Log. |
The Override Tab
The Override tab is only used for Kafka client 0.8 and controls how to determine which partition to use.
