I agree .. the problem is DC/OS still ships the older version. Let me check
if I can upgrade this ..
Thanks!

Thanks a lot for the response. I think what may be happening is a version
mismatch between the development & deployment versions of Kafka. The Kafka
streams application that I developed uses 0.10.0 based libraries. And my

Hi all,

Hey,
we just added a new FAQ entry for upcoming CP 3.2 release that answers
your question. I just c&p it here. More concrete answer below.

Hi,
We have a 3-node cluster that is running 0.9.0.1, and recently saw that the
"__consumer_offsets" topic on one of the nodes seems really skewed with
disk usage that looks like:
73G ./__consumer_offsets-10
0 ./__consumer_offsets-7
0 ./__consumer_offsets-4
0 ./__consumer_off
Hello All,
I have a Kafka Cluster deployed on AWS.

produced and consumed. But th
I wouldn't use synchronous replication between two datacenters. If your
network link ever goes down all Kafka writes will fail. If you ever need to do
maintenance you'll either need to somehow turn this off or all kafka writes
will fail. Plus, as Hans mentions, this will slow down your thro
Are you willing to have a maximum throughput of 6.67 messages per second?

I don't know of anything to handle that situation for you, but your application
can be written to do that.

What is the latency between the two datacenters? I ask because unless they are
very close, you probably don’t want to do any form of synchronous replication.
The Confluent Replicator (coming very soon in Confluent Enterprise 3.1) will do
async replication of both messages and configuration metad

I am actually using 0.10.0 and NOT 0.10.1 as I mentioned in the last mail.
And I am using Kafka within a DC/OS cluster under AWS.
The version that I mentioned works ok is on my local machine using a local

scenario.
Thanks.
