This feature is currently in incubating state, i.e. exact semantics, configuration options etc. may change in future revisions, based on the feedback we receive. Please let us know if you encounter any problems while using this extension.
Debezium provides a ready-to-use application that streams change events from a source database to messaging infrastructure like Amazon Kinesis or Google Pub/Sub.
For streaming change events to Apache Kafka, it is recommended to deploy the Debezium connectors via Kafka Connect.

The source configuration uses the same configuration properties that are described on the specific connector documentation pages (just with `debezium.source` prefix), together with few more specific ones, necessary for running outside of Kafka Connect:
The server supports https://cwiki.apache.org/confluence/display/KAFKA/KIP-66%3A+Single+Message+Transforms+for+Kafka+Connect[single message transformations] defined by Kafka Connect.
The configuration will need to contain the list of transformations, implementation class for each transformation and configuration options for each of the transformations.
[cols="35%a,10%a,55%a",options="header"]
|=======================
|Property
|Default
|Description
|`debezium.transformations`
|
|The comma separated list of symbolic names of transformations.
|`debezium.transformations.<name>.class`
|
|The name of Java class implementing the transformation with name `<name>`.
|`debezium.transformations.<name>.*`
|
|Configuration properties passed to the transformation with name `<name>`.
|=======================
=== Sink configuration
Sink configuration is specific for each sink type.
Currently the only supported sink is https://aws.amazon.com/kinesis/[Amazon Kinesis].
The sink is selected by configuration property `debezium.sink.type`.
* customization of an existing sink - i.e. non-standard configuration
=== Implementation of a new sink
The new sink can be implemented as a CDI bean implementing interface `DebeziumEngine.ChangeConsumer` and with annotation `@Named` and unique name and scope `@Dependent`.
See the https://github.com/debezium/debezium/blob/master/debezium-server/src/main/java/io/debezium/server/kinesis/KinesisChangeConsumer.java[Kinesis sink] implementation for further details.
