Change Data Capture (CDC) tools automatically track and replicate database changes in real time. Different mechanisms like log-based, trigger-based, query-based, timestamp-based, and hybrid CDC tools are used. Debezium is a popular open-source CDC platform with high scalability, integrating well with Kafka. Other tools like DBConvert Streams, Maxwell Daemon, and Sequin offer various features and integrations for efficient data replication. Challenges such as setup complexity and performance overhead are common with these tools.
