Hi, The documentation for new producer allows passing ack=2(or any other numeric value) but when i actually pass anything other than 0,1,-1 in broker log i see following warning.
Client producer-1 from /X.x.x.x:50105 sent a produce request with request.required.acks of 2, which is now deprecated and will be removed in next release. Valid values are -1, 0 or 1. Please consult Kafka documentation for supported and recommended configuration I have a particular use case where i want replication to be acknowledged by exactly (replicationFactor -1 ) broker or message publish should fail if that many Acks are not possible. regards
