Configuring the Adapter

1) To Create a new Adapter, open Dashboard > Deployment > Configuration

2) Search for Kafka Consumer Stream Service, and click Next

3) Define a name and description, and click Next

4) Define Bootstrap Server and Topic, and click Next

5) In Deserializer, click Next

6) In properties, click Next

7) Choose to write the file to a Mailbox, and click Next

8) Define a Mailbox to write the file , and click Next

9) Click Next and Finish

Now this adapter will use BP KafkaStreamServiceMailbox to monitor topics and write to mailboxes.
