To use an SDK to connect to a Message Queue for Apache Kafka instance and send and subscribe to messages, you must specify an endpoint based on the network type of the instance. You can view the endpoint of your instance in the Message Queue for Apache Kafka console.

Background information

Message Queue for Apache Kafka provides the following types of endpoints:

  • Default endpoint: It is used to send and subscribe to messages in a virtual private cloud (VPC), but does not support Simple Authentication and Security Layer (SASL) authentication.
  • SASL endpoint: It is used to send and subscribe to messages in a VPC, and supports SASL authentication.
  • Secure Sockets Layer (SSL) endpoint: It is used to send and subscribe to messages over the Internet, and supports SASL authentication.

For more information about differences among these endpoints, see Comparison among endpoints.

Procedure

  1. Log on to the Message Queue for Apache Kafka console.
  2. In the Resource Distribution section of the Overview page, select the region where your instance resides.
  3. On the Instances page, click the name of the instance that you want to manage.
  4. On the Instance Details page, view the endpoint of the instance in the Endpoint section.
    Note
    • If the value of Instance Type is VPC Type, only Default Endpoint is displayed.
    • If the value of Instance Type is Internet and VPC Type, both Default Endpoint and SSL Endpoint are displayed.
    • By default, SASL endpoints are not configured for instances. Therefore, by default, SASL endpoints are not displayed. To use SASL endpoints, you must apply for authorization. For more information, see Authorize SASL users.

What to do next

After you obtain the endpoint of your Message Queue for Apache Kafka instance, you can use the SDK to connect to the instance and send and subscribe to messages. For more information, see SDK overview.
