It will guide you through the configuration. You can activate the wizard for reconfiguration anytime later from the toolbar.

The Setup Wizard displays two bridge options while both are disabled initially:

Click Enable this feature to configure it.

Create a Pulsar to Kafka Bridge

A bridge is created between topics of a Pulsar source and a Kafka target broker. They can be local or cloud-based brokers. This example bridges topic topic1 on the Pulsar broker running on Kesque to topic topic1 of a Kafka broker running on Confluent Cloud.

  • You first define a unique bridge name that is used in dashboards.

  • Then enter the Pulsar server URL, authentication token, topic, and subscription name etc to define the source for the bridge.

  • Since we use a Confluent Cloud broker, you can copy the properties from their web site to configure the Kafka Producer or fine-tune it according to your needs.

  • Specify the target topic name. Only a single topic is allowed here.

  • We specify a key that is set for every produced message.

That’s it.

You can create more bridges by clicking the + button:

Create a Kafka to Pulsar Bridge

This creates a bridge between one or more Kafka topics and a Pulsar topic. In this example, we bridge from the Confluent Cloud Kafka broker to the Kesque Pulsar broker:

  • Specify the broker properties and source topic name. If you want to bridge from multiple topics, separate them by a comma.

  • Specify the Pulsar server URL, authentication token, topic, and optionally a key.

You can create more bridges by clicking the + button:

Remove a Topic Bridge
