Announcing the Amazon EventBridge Sink Connector for Apache Pulsar

Baodi Shi
Platform Engineer at StreamNative

StreamNative is excited to announce the general availability of the Amazon EventBridge sink connector for Apache Pulsar. This connector synchronizes Pulsar data to Amazon EventBridge in real-time, enabling Google Amazon EventBridge to leverage Pulsar and expand the Apache Pulsar ecosystem.

What is the Amazon EventBridge sink connector?

The Amazon EventBridge sink connector pulls data from Pulsar topics and persists data to AWS EventBridge.

Why we built the Amazon EventBridge sink connector?

AWS EventBridge is a serverless service that uses events to connect application components together, making it easier to build scalable event-driven applications. 

Sending data from Apache Pulsar to AWS EventBridge can provide several benefits:

  • AWS EventBridge can act as a central hub for processing and routing events from various sources, including Apache Pulsar. This can enable teams to build a unified event-driven architecture that can handle events from different systems and applications.
  • AWS EventBridge provides a wide range of event targets, such as AWS Lambda, Amazon SNS, Amazon SQS, etc., that can be used quickly to access the AWS ecosystem. This can enable teams to build event-driven workflows that can automate business processes and reduce manual intervention.
  • AWS EventBridge provides built-in security and compliance features, such as AWS CloudTrail integration, AWS Identity and Access Management (IAM) policies, and encryption at rest and in transit. This can help ensure the confidentiality, integrity, and availability of event data.

Therefore, StreamNative developed this connector to provide an easy way for teams to write data from Pulsar to EventBridge in real time.

Benefits of the Amazon EventBridge sink connector?

The integration between Amazon EventBridge and Apache Pulsar provides four key benefits.

  • Simplicity: Quickly move data from Apache Pulsar to Amazon EventBridge without requiring any code
  • Efficiency: Reduce the time in configuring the data layer. This means that teams can spend more time building their business use cases instead of configuring their data. 
  • Scalability: Run the EventBridge connector in different modes (standalone or distributed). This allows teams to build reactive data pipelines to meet business and operational needs in real-time.

Get started with the Amazon EventBridge sink connector

> For StreamNative Cloud users, do refer to this blog to create a connector on StreamNative Cloud quickly.


First, you must run an Apache Pulsar cluster and an Amazon EventBridge service.

  1. Prepare the Pulsar service. You can quickly run a Pulsar cluster anywhere by running `$PULSAR_HOME/bin/pulsar standalone`. Refer to the documentation for details.
  2. Prepare the AWS EventBridge service. See Getting Started with Amazon EventBridge for details. Need to create EventBus and Rule first.
  3. Set up the AWS EventBridge connector. Download the connector from the Releases page, and then move the nar package to `$PULSAR_HOME/connectors`.

Apache Pulsar provides a Pulsar IO feature to run the connector. Follow the steps below to get the connector up and running.

Configure the sink connector

1. Create a configuration file named aws-eventbridge-sink-config.json. The configured connector writes the message in the public/default/aws-eventbridge-pulsar topic to the pulsar-event-bus-name event bus of EventBridge.

	"name": "eventbridge-sink",
	"archive": "connectors/pulsar-io-aws-eventbridge-",
	"tenant": "public",
	"namespace": "default",
	"inputs": [
	"parallelism": 1,
	"configs": {
		"accessKeyId": "{{Your access access key}}",
		"secretAccessKey": "{{Your secret access key}}",
		"region": "test-region",
		"eventBusName": "pulsar-event-bus-name"

2. Run the sink connector.

PULSAR_HOME/bin/pulsar-admin sinks localrun --sink-config-file aws-eventbridge-sink-config.json

3. You can send messages to the `public/default/aws-eventbridge-pulsar` topic, then view it in EventBridge.
