A. Sophie Blee-Goldman commented on KAFKA-8531: ----------------------------------------------- Hey [~mjsax], are you planning to knock this out for 3.0? And can we really piggyback this change on [KIP-464|https://cwiki.apache.org/confluence/display/KAFKA/KIP-464%3A+Defaults+for+AdminClient%23createTopic]? Kind of seems like it might merit a quick KIP of its own > Change default replication factor config > ---------------------------------------- > > Key: KAFKA-8531 > URL: https://issues.apache.org/jira/browse/KAFKA-8531 > Project: Kafka > Issue Type: Improvement > Components: streams > Affects Versions: 2.3.0 > Reporter: Matthias J. Sax > Assignee: Matthias J. Sax > Priority: Blocker > Labels: kip > Fix For: 3.0.0 > > > With KAFKA-8305, AdminClient allows to create topics based on the broker > default replication factor. > Kafka Streams sets `replication.factor` to 1 by default atm, to give a good > out-of-the-box user experience. The problem is, that people may need to > change the config if they push an application to production. > We should change the default to `-1` to exploit the new AdminClient feature. > This won't impact the out-of-the-box experience and may avoids the need to > change the setting when pushing an application to production. > We piggy-back this change to the original KIP: > [https://cwiki.apache.org/confluence/display/KAFKA/KIP-464%3A+Defaults+for+AdminClient%23createTopic] -- This message was sent by Atlassian Jira (v8.3.4#803005)
