Hello folks, Was doing stress tests and realized that the replication to the target cluster and thus the configuration of the KafkaProducer has a default acks of -1 ( all ) and that was prohibitively expensive. It should have been a simple a->b.producer.acks = 1 ( or b.producer.acks = 1 or acks = 1, have tried all ) override in the mm2.properties, but it does not take. I verified by turning on TRACE and a little instrumenting the code to print out the acks . https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/producer/internals/Sender.java#L806 . Am I missing something?
Regards
