there is no equivalent concept of exchange in Pulsar. I think the closest one is probably "Topic" in Pulsar. At StreamNative, we added a native RabbitMQ protocol handler for Pulsar (https://github.com/streamnative/aop). This protocol handler implements the RabbitMQ concepts based on Pulsar. We have also written an article about how we map RabbitMQ concepts to Pulsar concepts. https://streamnative.io/blog/amqp-pulsar-bring-native-amqp-protocol-support-to-apache-pulsar This can help you understand the Pulsar concept better. Here are a few other references: https://streamnative.io/blog/how-to-migrate-from-rabbitmq-to-apache-pulsar https://streamnative.io/blog/comparison-of-messaging-platforms-apache-pulsar-vs-rabbitmq-vs-nats-jetstream Hope this is helpful for you. Happy to discuss your use cases and see how we can help you.
