Enabling Smart Connect

Smart Connect synchronizes data between Kafka and other cloud services (such as OBS) or between two Kafka instances for backup or migration.

Procedure for using Smart Connect:

  1. Enable Smart Connect.
  2. Create a Smart Connect task.

This section describes how to enable Smart Connect.

Notes and Constraints

  • Enabling Smart Connect incurs additional broker fees.

    For example, if you enable Smart Connect for a kafka.4u8g.cluster instance, at least two more kafka.4u8g brokers will be created for Smart Connect and you need to pay for them.

  • Unavailable for single-node instances.

Prerequisites

Procedure

  1. Log in to the console.
  2. Click in the upper left corner to select the region where your instance is located.
  3. Click in the upper left corner and choose Middleware > Distributed Message Service (for Kafka) to open the console of DMS for Kafka.
  4. In the navigation pane, choose Kafka Instances.
  5. Enable Smart Connect using one of the following methods:

    • In the row containing the desired Kafka instance, choose More > Enable Smart Connect.
    • Click the desired Kafka instance to go to the instance details page. In the upper right corner, choose More > Enable Smart Connect.
    • Click the desired Kafka instance to go to the instance details page. Click next to Smart Connect.
    • Click the desired Kafka instance to go to the instance details page. In the navigation pane, choose Smart Connect. Click Enable Smart Connect.

  6. Click , enable Smart Connect, set 2–16 brokers as required, and click Next.

    By default, two brokers will be used. If synchronization traffic between two Kafka instances is estimated to be large, for example, greater than 50 MB/s, use more brokers.

  7. On the displayed Enabling Smart Connect for Kafka Instance page, ensure that Smart Connect is enabled and click Submit.

Follow-up Operations

Proceed to Replicating Kafka Instance Data, Dumping Kafka Data to Object Storage Service (OBS), to synchronize data between DMS for Kafka and other cloud services.
