TimestampRouter¶
The following provides usage information for the Kafka SMT org.apache.kafka.connect.transforms.TimestampRouter.
Description¶
Update the record’s topic field as a function of the original topic value and the record timestamp.
This is useful for sink connectors, because the topic field often determines the equivalent entity name in the destination system (for example, a database table or search index name). See MessageTimestampRouter to extract the timestamp from a specified message field.
Example¶
This configuration snippet shows how to use TimestampRouter to route
messages to topics and include a formatted timestamp.
