Jason Rosenberg commented on KAFKA-1028: ---------------------------------------- Can you clarify, is this different than using request.required.acks = 2, always? (e.g. if there's only one broker in the ISR, no messages can be acknowledged). > 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 > Assignee: Neha Narkhede > > 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. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
