Hello I am using librdkafka c++ library for my application .
*My Kafka Cluster Set up* 2 Kafka Zookeper running on 2 different instances 7 Kafka Brokers , 4 Running on 1 machine and 3 running on other machine Total 10 Topics and partition count is 3 with replication factor of 3. Now in my case I need to be very specific for the *message order* when I am consuming the messages. I know if all the messages gets produced to the same partition, it always gets consumed in the same order. I need expert opinions like what's the ideal partition count I should consider without effecting performance.( I am looking for close to 100,000 messages per seconds). The topics are from 0 to 9 and when I am producing messages I do something like uniqueUserId % 10 , and then pointing to a respective topic like 0 || 1 || 2 etc.. Abhi -- If you can't succeed, call it version 1.0
