A collection of Simple Message Transformation (SMT) for Apache Kafka Connect

Building the code

Transformations

InsertHeaderCurrentTimestamp

This transformation inserts the current system timestamp into the header. It is beneficial when there is a need to capture the time at which the record is processed, for example, when Sink connectors consume a record. It enables deriving information about the delay between the record's production time and its consumption time.
