-------------------------------------

Hi [~ivanyu],

As of present, the replication-level client configuration is not working 
correctly (although the MirrorMakerConfig's Javadoc states that it works); and 
[this 
KIP|https://cwiki.apache.org/confluence/display/KAFKA/KIP-781%3A+Improve+MirrorMaker2%27s+client+configuration]
 (KAFKA-13365) states the rule for replication-level client configuration like 
the following:
{quote}{{A->B.producer.\{property-name}}} and {{A->B.admin.\{property-name}}} 
are applied to target cluster clients and {{A->B.consumer.\{property-name}}} is 
applied to source cluster clients.
{quote}
If not, please leave a message on the mailing list 
[here|https://lists.apache.org/thread.html/r2ab9df6e620eb3ac8a0e1dd7a2f833b1978452aa6bec21c38c1dde18%40%3Cdev.kafka.apache.org%3E].

>             Project: Kafka
>          Issue Type: Bug
>          Components: mirrormaker
>            Reporter: Ivan Yurchenko
>            Priority: Minor
>
> Currently, it's possible to set producer and consumer configurations for a 
> cluster in MirrorMaker 2, like this:
> {noformat}
> {source}.consumer.{consumer_config_name}
> {target}.producer.{producer_config_name}
> {noformat}
> However, in some cases it makes sense to set these configs differently for 
> different replication flows (e.g. when they have different latency/throughput 
> trade-offs), something like:
> {noformat}
> {source}->{target}.{source}.consumer.{consumer_config_name}
> {source}->{target}.{target}.producer.{producer_config_name}
> {noformat}
