Diego Erdody updated KAFKA-13431: --------------------------------- Labels: needs-kip (was: ) > Sink Connectors: Support topic-mutating SMTs for async connectors (preCommit > users) > ----------------------------------------------------------------------------------- > > Key: KAFKA-13431 > URL: https://issues.apache.org/jira/browse/KAFKA-13431 > Project: Kafka > Issue Type: Improvement > Components: KafkaConnect > Reporter: Diego Erdody > Assignee: Diego Erdody > Priority: Major > Labels: needs-kip > > There's currently an incompatibility between Sink connectors overriding the > {{SinkTask.preCommit}} method (for asynchronous processing) and SMTs that > mutate the topic field. > The problem was present since the {{preCommit}} method inception and is > rooted in a mismatch between the topic/partition that is passed to > {{open/preCommit}} (the original topic and partition before applying any > transformations) and the topic partition that is present in the SinkRecord > that the {{SinkTask.put}} method receives (after transformations are > applied). Since that's all the information the connector has to implement any > kind of internal offset tracking, the topic/partitions it can return in > preCommit will correspond to the transformed topic, when the framework > actually expects it to be the original topic. -- This message was sent by Atlassian Jira (v8.3.4#803005)
