Hi, I would like to propose a change in the kafka-consumer-perf-test tool to support perf testing specific partitions.
kafka-consumer-perf-test is a great tool to quickly check raw consumer performance. Currently, It subscribes to all the partitions and gives overall cluster performance, however If we want to test performance of a single broker/partition, existing tool does not support it. I propose two optional flags --partitions and --offsets which gives flexibility to benchmark only specific partitions optionally from specified offsets.
