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
