Oracle-to-Couchbase real-time data pipeline using Debezium CDC, Kafka, and schema-managed streaming. A Python generator populates Oracle, Debezium captures changes via CDC connector, Kafka brokers the stream with Avro schema validation, and a Couchbase Sink Connector materializes data into a NoSQL store. The architecture demonstrates event-driven data flow from transactional source through streaming platform to serving layer, enabling raw, curated, and aggregated data tiers in Couchbase and downstream data lake. Fork this diagram to customize connectors, add transformation logic, or adapt for your source and sink systems.
