Thank you for answer. This is where the TimestampConverter comes in. Because ksqlDB defaults to using the timestamp metadata of the underlying Kafka records, you need to tell ksqlDB where to find the timestamp attribute within the events. Heres an example of the JDBC sink connector (See also Kafka Connect in Action : JDBC Sink ( demo code) and ksqlDB & Kafka Connect JDBC Sink in action ( demo code)): Note that txn_date is a text field, which is no use for anyone who wants to use it as the timestamp that it is.

In the payload the txn_date field looks like a timestamp: But if we have a look at the actual schema for the value (since its serialised as Avro; the same would apply for Protobuf or JSON Schema) we can see that it might look like a timestamp, quack like a timestamp, but is in fact not a timestamp per se, but a string: This means that when the data is used by a consumer, such as a Kafka Connect sink, its still handled as a string with the result that the target object type will usually inherit the same.
