In this blog, the author demonstrates how to set up and configure the MongoDB Connector for Apache Kafka using Azure Event Hubs as an alternative to running a Kafka cluster. The author creates an Azure Event Hub and uses Docker to spin up a Kafka Connect container with the MongoDB Connector for Apache Kafka. They then define the source and sink connectors to push data from a MongoDB collection into the Azure Event Hub and back to another MongoDB collection, respectively. The author uses Python to insert data into the source collection and read data from the sink collection, demonstrating a round-trip of data sent through Azure Event Hubs using the MongoDB Connector for Apache Kafka.
