Scott Clasen created KAFKA-1028:
-----------------------------------

             Summary: per topic configuration of preference for consistency over availability
                 Key: KAFKA-1028
                 URL: https://issues.apache.org/jira/browse/KAFKA-1028
             Project: Kafka
          Issue Type: Improvement
            Reporter: Scott Clasen


As discussed with Neha on the ML.

It should be possible to configure a topic to disallow unclean leader election, thus preventing the situation where committed messages can be discarded once a failed leader comes back online in a situation where it was the only ISR.

This would open kafka to additional usecases where the possibility of committted messages being discarded is unacceptable.
