Reliable event publishing. Learn how to bridge your database and Kafka using the Outbox pattern and Debezium CDC.
The Dual Write Problem occurs when you update your DB and then try to send an event to Kafka. If the Kafka send fails, your DB and downstream systems are out of sync.
Write the event to an table in the same local transaction as your business data. A separate process (like Debezium) then reads the DB transaction logs and publishes the event to Kafka.
