This guide provides a step-by-step walkthrough of setting up and using PostgreSQL Change Data Capture (CDC) with Kafka and Propel to stream real-time data from PostgreSQL databases into a Kafka topic, then serve the data via an API. The process involves setting up Minikube, PostgreSQL, Kafka, Kafka Connect, Debezium, and creating a Propel Kafka Data Pool. The resulting setup allows for efficient tracking and capturing of changes to your data in near real-time with minimal impact on source systems.
