Hey Samuel,
I am facing a similar issue with the partitions.assignment.strategy
consumer setting on MM2.
Let me know if you have any success with setting this (I am also interested
with the auto.offset.reset config as well but its a lower priority for my
testing. I assume the solution will be
Hello,
Following our experimenting with MM2, we seem to have a hard time
recovering from lags created by increased traffic.
Since we're running MM2 on kubernetes, we can easily add more
resources/instances to our MM2 cluster, which should in theory increase the
clusters performance and allow us
Hello,
Whenever we add a new topic to the mirroring whitelist it starts to mirror
the entire content of the source topic. If the topic is large this can
create a long lag until the entire topic is mirrored, and it can also
create some smaller delays on other mirrored topics (i'm assuming this is
Hello,
I'm seeing large lag sometimes on my MM2 clusters after restarting the
cluster (it runs on k8s).
I have 3 mm2 clusters, each one reads from 1 source and writes to the same
destination.
I am seeing these errors on one of my clusters right now.

Hello
I'm running a mirrormaker 2 cluster which copies from 3 source clusters
into 1 destination. Yesterday I restarted the cluster and it took 1 of the
mirrored topics a pretty long time to recover (2~ hours)
Since the restart the mm2 cluster has been sending a lot of these warning
messages
Got it. Thanks!

Hello,
I want to monitor our mirrormaker 2 cluster using prometheus. We are mostly
interested in lag, incoming/outgoing traffic and java related metrics.
Does anyone have experience with this? Should I use the kafka prometheus
jmx exporter or some other exporter for this? (kafka connect exporter

Hello,
Up until now we have configured compression on producer level. Since moving
to mm2, we are having some issues with producer level compression and mm2,
and are planning on trying out topic level compression for this case.
Are there any inherent differences to each method other than
I believe I got it to work with "source->dest.producer.compression.type =
gzip"
Is there a way to set this globally for the mm2 process and not to do it
per mirroring flow?
Thanks,

Hello everyone.
I'm testing mm2 for our cross dc topic replication. We used to do it using
mm1 but faced various issues.
So far, mm2 is working well, but I have 1 issue which I can't really
explain; the destination topic is larger than the source topic.
For example, We have 1 topic which on the
Hello,
Currently we are using mm1 to copy from several DCs into aggregated kafka
clusters. The name of the source and destination topics are the same.
MM2 adds the source cluster prefix automatically and this causes issues for
our use case. Is there a way to tell MM2 to not create the source
