Kafka

Send processed data from Unstructured to Kafka.

The requirements are as follows.

• A Kafka cluster, such as ones offered by the following providers:

  • Confluent Cloud (Create a cluster.)

    The following video shows how to set up a Kafka cluster in Confluent Cloud:

  • Amazon Managed Streaming for Apache Kafka (Amazon MSK) (Create an Amazon MSK Provisioned cluster, or create an Amazon MSK Serverless cluster.)

  • [Apache Kafka in Azure HDInsight] (Create an Apache Kafka cluster in Azure HDInsight.)

  • Google Cloud Managed Service for Apache Kafka (Create a cluster.)

• The hostname and port number of the bootstrap Kafka cluster to connect to.

  • For Confuent Cloud, get the hostname and port number.
  • For Amazon MSK, get the hostname and port number.
  • For Apache Kafka in Azure HDInsight, get the hostname and port number.
  • For Google Cloud Managed Service for Apache Kafka, get the hostname and port number.

• The name of the topic to read messages from and write messages to on the cluster.

  • For Confluent Cloud, create a topic and access available topics.
  • For Amazon MSK, create a topic on an Amazon MSK Provisioned cluster, or create a topic on an Amazon MSK Serverless cluster.
  • For Apache Kafka in Azure HDInsight, create a topic and access available topics.
  • For Google Cloud Managed Service for Apache Kafka, create a topic and access available topics.

• If you use Kafka API keys and secrets for authentication, the key and secret values.

  • For Confluent Cloud, create an API key and secret.
  • For Amazon MSK, create an API key and secret.
  • For Apache Kafka in Azure HDInsight, create an API key and secret.
  • For Google Cloud Managed Service for Apache Kafka, create an API key and secret.

To create the destination connector:

1. On the sidebar, click Connectors.
2. Click Destinations.
3. Cick New or Create Connector.
4. Give the connector some unique Name.

• Name (required): A unique name for this connector.
• Bootstrap Server (required): The hostname of the bootstrap Kafka cluster to connect to.
• Port: The port number of the cluster.
• Group ID: The ID of the consumer group, if any, that is associated with the target Kafka cluster. (A consumer group is a way to allow a pool of consumers to divide the consumption of data over topics and partitions.) The default is default_group_id if not otherwise specified.
• Topic (required): The unique name of the topic to read messages from and write messages to on the cluster.
• Number of messages to consume: The maximum number of messages to get from the topic. The default is 1 if not otherwise specified.
• Batch Size: The maximum number of messages to send in a single batch.
• API Key (required): The Kafka API key value.
• Secret (required): The secret value for the Kafka API key.
