The Kafka profile enables you to configure which topic and which embedded service key to use, and it is loaded when you start a workflow that depends on it. Changes to the profile become effective when you restart the workflow. The Kafka profile configuration contains two tabs: Connectivity and Advanced. Connectivity tabThe Connectivity tab is displayed by default when creating or opening a Kafka profile, and it contains the following settings: Setting | Description |
|---|
Topic | Enter the Kafka topic that you want to use for your configuration. For information on how to create a Kafka topic, refer to /wiki/spaces/MD/pages/3214953. This field supports parameterization using ${} syntax, see Profiles(3.0) for more information on how parameterization works. | Use parameterized broker list | Enable this checkbox if you like to set Brokers as a parameter instead. When enabled you need to set parameter name using ${} syntax, see Profiles(3.0) for more information on how parameterization works. | Brokers | A Broker is a node in a Kafka cluster. If you are using external Kafka, you must add Kafka Brokers. Use the Add button to enter the addresses of the Kafka Brokers that you want to connect to. | Host | If you are using external Kafka, enter the host name for Zookeeper. | Port | If you are using external Kafka, enter the port for Zookeeper. | Group id | Set this id to an identity of your choice, to enable load sharing between several Kafka collectors. Use this in combination with enable.auto.commit=true, in the Consumer and Advanced tab. This field supports parameterization using ${} syntax, see Profiles(3.0) for more information on how parameterization works. | Security Profile | Connect the Security (3.0), in the case you have defined it for your Kafka server. |
Advanced tabIn the Advanced tab you can configure properties for optimizing the performance of the Kafka Producer and Consumer. The Advanced tab contains two tabs: Producer and Consumer. | Note |
|---|
Note! If you make any changes to the security configuration of the Kafka Producer, any topics used must be recreated before they can be used. |
Producer tabIn the Producer tab, you can configure the properties of the Kafka forwarding agent. The property producer.abortunknown=true sets the agent to abort if the broker replies with Unknown topic or partition. For further information on the other properties, see the text in the Advanced producer properties field, or refer to https://kafka.apache.org/25/documentation.html#producerconfigs. When running in Acknowledged execution mode, the property producer.full.response determines if the data sent to the kafka log is also included in the response UDR. The value is set to true by default. Setting the value to false reduces the memory footprint. For information on how to configure the properties for SSL and Kerberos, please refer to https://www.cloudera.com/documentation/kafka/latest/topics/kafka_security.html. This field supports parameterization using ${} syntax. For more information on parameterization see Profiles(3.0). Consumer tabIn the Consumer tab, you can configure the properties of the Kafka collection agent. For further information about the properties, see the text in the Advanced consumer properties field, or refer to https://kafka.apache.org/25/documentation.html#consumerconfigs. This field supports parameterization using ${} syntax. For more information on parameterization see Profiles(3.0). |
