devbv commented on issue #3072: Enhance kafka message provider URL: https://github.com/apache/incubator-openwhisk/pull/3072#issuecomment-354724456 @markusthoemmes I think some types of RetriableException could duplicate a message if we tried to send a message again. I'm pretty sure that InvalidMetadata guarantees that we really fail to send a message, but cannot sure it when TimeoutException is raised. And you can see here, producer retries will cause duplicates for NotEnoughReplicasAfterAppendException https://kafka.apache.org/0100/javadoc/org/apache/kafka/common/errors/NotEnoughReplicasAfterAppendException.html
