2. In the left-side navigation pane, choose Connector Ecosystem Integration > Tasks.

3. On the Tasks page, click Create Task.

4. On the Create Task page, configure the Task Name and Description parameters and follow the on-screen instructions to configure other parameters. Then, click Save. The following section describes the parameters:

   • Task Creation

     1. In the Source step, set the Data Provider parameter to ApsaraMQ for Kafka and follow the on-screen instructions to configure other parameters. Then, click Next Step. The following table describes the parameters.

        Parameter	Description	Example
        Region	The region where the source ApsaraMQ for Kafka instance resides.	China (Beijing)
        ApsaraMQ for Kafka Instance	The ApsaraMQ for Kafka instance in which the messages that you want to route are produced.	MQ_INST_115964845466****_ByBeUp3p
        Topic	The topic on the ApsaraMQ for Kafka instance in which the messages that you want to route are produced.	topic
        Group ID	The name of the consumer group on the source ApsaraMQ for Kafka instance. You must use a separate consumer group to create the message routing source. Do not use a consumer group that is in use. Otherwise, existing messages may fail to be sent and received.	GID_http_1
        Consumer Offset	The offset from which messages are consumed.	Latest Offset
        Network Configuration	The type of the network over which you want to route messages.	Basic Network
        VPC	The ID of the virtual private cloud (VPC) in which the ApsaraMQ for Kafka instance is deployed. This parameter is required only if you set the Network Configuration parameter to Self-managed Internet.	vpc-bp17fapfdj0dwzjkd****
        vSwitch	The ID of the vSwitch with which the ApsaraMQ for Kafka instance is associated. This parameter is required only if you set the Network Configuration parameter to Self-managed Internet.	vsw-bp1gbjhj53hdjdkg****
        Security Group	The security group to which the ApsaraMQ for Kafka instance belongs. This parameter is required only if you set the Network Configuration parameter to Self-managed Internet.	alikafka_pre-cn-7mz2****
        Messages	The maximum number of messages that can be sent in each function invocation. Requests are sent only when the number of messages in the backlog reaches the specified value. Valid values: 1 to 10000.	100
        Interval (Unit: Seconds)	The time interval at which the function is invoked. The system sends the aggregated messages to Function Compute at the specified time interval. Valid values: 0 to 15. Unit: seconds. The value 0 specifies that messages are sent immediately after aggregation.	3

     2. In the Filtering step, define a data pattern in the Pattern Content code editor to filter requests. For more information, see Event patterns.

     3. In the Transformation step, specify a data cleansing method to implement data processing capabilities such as splitting, mapping, enrichment, and dynamic routing. For more information, see Data cleansing.

     4. In the Sink step, set the Service Type parameter to ApsaraMQ for Kafka and follow the on-screen instructions to configure other parameters. The following table describes the parameters.

        Parameter	Description	Example
        Instance ID	The destination ApsaraMQ for Kafka instance that you created.	test
        Topic	The topic on the destination ApsaraMQ for Kafka instance that you created.	test
        Acknowledgment Mode	The mode that ApsaraMQ for Kafka uses to acknowledge the received data. None LeaderOnly All	None
        Message Value	EventBridge extracts data from a message by using JSONPath and routes the specified content of the message to the event target. Complete Data Data Extraction Fixed Value Template	Data Extraction $.data.value
        Message Key	EventBridge extracts data from a message by using JSONPath and routes the specified content of the message to the event target. Empty Data Extraction Fixed Value Template	Data Extraction $.data.key

   • Task Property

     Configure the retry policy and dead-letter queue for the task. For more information, see Retry policies and dead-letter queues.

5. Go back to the Tasks page, find the ApsaraMQ for Kafka sink connector that you created, and then click Enable in the Actions column.

6. In the Note message, click OK.

   The connector requires 30 to 60 seconds to be enabled. You can view the progress in the Status column on the Tasks page.
