Active-Active Inter-cluster synchronization

[devoss ind]

Hi,

I found a link @
http://users.kafka.apache.narkive.com/RKtnfWBr/active-active-inter-cluster-synchronization
related to inter-cluster data replication. I have a similar requirement to
have data replicated on remote datacenter cluster and have global view. I
did not understand from the above link how can we separate out write
cluster and read cluster within data center? It would be better if its
explained in terms of deployment including zookeeper.

Thanks in advance..

Multiple producer instances choose same partition

[devoss ind]

Hi,

Am a newbie to Kafka and would like to use it. I have a question regarding
the same partition selection from multiple producers. Assume that I did not
specify any key while sending a message from producer and let producer to
choose partition in a round-robin manner. I have multiple producer nodes
(i.e., running in different machines) and if all nodes choose the same
partition for the messages to be sent, will there be any locking of the
partition log at broker? Will there be any performance problems at the
broker while writing messages to same partition produced from different
producers?

Thanks,
Devoss.
