Class ConvertCloudEventToSaveableForm

java.lang.Object

io.debezium.connector.jdbc.transforms.ConvertCloudEventToSaveableForm

All Implemented Interfaces:

Closeable, AutoCloseable, org.apache.kafka.common.Configurable, org.apache.kafka.connect.components.Versioned, org.apache.kafka.connect.transforms.Transformation<org.apache.kafka.connect.sink.SinkRecord>

public class ConvertCloudEventToSaveableForm
extends Object
implements org.apache.kafka.connect.transforms.Transformation<org.apache.kafka.connect.sink.SinkRecord>, org.apache.kafka.connect.components.Versioned

The transform converts a CloudEvent to a structure suitable for `JdbcSinkConnector`
