The article demonstrates how to move data from Oracle to MongoDB using Apache Kafka, Confluent Oracle CDC Connector, and MongoDB Connector for Apache Kafka. The process involves configuring a self-contained Docker environment with Oracle Database, MongoDB, Apache Kafka, and Confluent KSQL. The Oracle database is configured to use the Confluent Oracle CDC Connector, which captures changes to the database and sends them to Apache Kafka. The MongoDB Connector for Apache Kafka consumes the events from Kafka and writes them to MongoDB. The process also includes creating a Kafka topic, configuring the Oracle CDC Connector, setting up KSQL data flows, and writing data to Oracle. The article provides step-by-step instructions and resources for getting started with this process.
