Debezium is an open-source distributed platform for change data capture (CDC) that enables applications to respond to real-time changes in databases. It streams inserts, updates, and deletes from databases such as MySQL, PostgreSQL, SQL Server, MongoDB, and Oracle into messaging systems like Apache Kafka, enabling downstream systems to react immediately to data changes. Debezium is widely used for building event-driven architectures, real-time analytics pipelines, and data replication solutions. It ensures consistency by reading transaction logs directly from databases and provides features like schema history, fault tolerance, and exactly-once semantics. With strong community support and integration into modern data stacks, Debezium has become a popular choice for organizations looking to unlock real-time data flows and keep systems synchronized.
