Neha Narkhede created KAFKA-1296: ------------------------------------ Summary: Improve error reporting in new mirror maker Key: KAFKA-1296 URL: https://issues.apache.org/jira/browse/KAFKA-1296 Project: Kafka Issue Type: Improvement Components: producer Affects Versions: 0.9.0 Reporter: Neha Narkhede Assignee: Neha Narkhede Priority: Critical
In the new mirror maker (like the old MM), the MM asynchronously sends data through the producer. Due to this, it doesn't have a way to get any exception that the producer sends back and do something meaningful. At least not without falling back to synchronous behavior. What this means is that if the producer runs out of retries, it silently drops data on the floor and the user is left wondering why the # of messages in the target cluster don't match with those in the source cluster. I think it is useful for the producer to log an error before returning the exception to the user. -- This message was sent by Atlassian JIRA (v6.2#6252)
