Debezium Architecture

Debezium Server

Another way to deploy Debezium is using the Debezium server. The Debezium server is a configurable, ready-to-use application that streams change events from a source database to a variety of messaging infrastructures.

The following image shows the architecture of a change data capture pipeline that uses the Debezium server:

The Debezium server is configured to use one of the Debezium source connectors to capture changes from the source database. Change events can be serialized to different formats like JSON or Apache Avro and then will be sent to one of a variety of messaging infrastructures such as Amazon Kinesis, Google Cloud Pub/Sub, or Apache Pulsar.

Embedded Engine

Yet an alternative way for using the Debezium connectors is the embedded engine. In this case, Debezium will not be run via Kafka Connect, but as a library embedded into your custom Java applications. This can be useful for either consuming change events within your application itself, without the needed for deploying complete Kafka and Kafka Connect clusters, or for streaming changes to alternative messaging brokers such as Amazon Kinesis. You can find an example for the latter in the examples repository.
