Chris Egerton created KAFKA-10720: ------------------------------------- Summary: Add note to Transformation docs to avoid mutating records or their members Key: KAFKA-10720 URL: https://issues.apache.org/jira/browse/KAFKA-10720 Project: Kafka Issue Type: Improvement Components: KafkaConnect Reporter: Chris Egerton
The public documentation for the {{Transformation}} interface does not mention whether an SMT should or should not mutate records or their members (such as their values or headers), but there's some logic in the Connect framework that relies on SMTs not doing this, such as the invocation of `SourceTask::commitRecord` with a pre-transformation record in some cases. We should consider adding a note about not modifying records or their members to the public-facing documentation for the {{Transformation}} interface. -- This message was sent by Atlassian Jira (v8.3.4#803005)
