Hi Himanshu, Pasting screenshot for better view. My Observations: * When I increased partitions, and keep replica same, then Throughput increases. Compare Row 1 and 2 * Increase number of replica and partitions same: Throughput decreased than before. Row 2 and 3 * Increase number of partitions and keep replica same as before: TP increased. Row 3 and 4 * Increase number of Replica and keep partitions same: TP decreased. Row 4 and 5.
Question: Does it make any impact on throughput when number of partitions and replicas are equal?

Example: MB1P1R= MB is my topic name with 1 Partition and 1 replica. I have 3 nodes cluster. My Observations: * When I increased partitions, and keep replica same, then Throughput increases. Compare Row 1 and 2 * Increase number of replica and partitions same: Throughput decreased than before. Row 2 and 3 * Increase number of partitions and keep replica same as before: TP increased. Row 3 and 4 * Increase number of Replica and keep partitions same: TP decreased. Row 4 and 5. Question: Does it make any impact on throughput when number of partitions and replicas are equal?
