Package io.debezium.connector.mongodb.transforms

Class ExtractNewDocumentState<R extends org.apache.kafka.connect.connector.ConnectRecord<R>>

java.lang.Object

io.debezium.transforms.AbstractExtractNewRecordState<R>

io.debezium.connector.mongodb.transforms.ExtractNewDocumentState<R>

Type Parameters:

R - the subtype of ConnectRecord on which this transformation will operate

All Implemented Interfaces:

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

public class ExtractNewDocumentState<R extends org.apache.kafka.connect.connector.ConnectRecord<R>>
extends AbstractExtractNewRecordState<R>

Debezium Mongo Connector generates the CDC records in String format. Sink connectors usually are not able to parse the string and insert the document as it is represented in the Source. so a user use this SMT to parse the String and insert the MongoDB document in the JSON format.
