Debezium is an open-source platform for Change Data Capture (CDC) that extracts transactional changes from databases and delivers them to consumers. While commonly used with Kafka, Debezium can also integrate with other messaging systems such as Apache Pulsar or RabbitMQ. It offers a Service Provider Interface (SPI) for custom sink adapters, enabling the creation of an Apache Iceberg Consumer. This consumer transforms CDC events into data files and commits them to Iceberg tables. By using Java API with each Debezium source topic mapped to a specific Iceberg table, it is ensuring efficient real-time data processing and storage.
