* Change default replication factor to -1 Binder now uses a default value of -1 for replication factor signaling the broker to use defaults. Users who are on Kafka brokers older than 2.4, need to set this to the previous default value of 1 used in the binder. In either case, if there is an admin policy that requires replication factor > 1, then that value must be used instead.
