------------------------------------------
Summary: Trogdor - Allow configuration for not throttling
Benchmark Workers and expose messages per second
Key: KAFKA-7599
URL: https://issues.apache.org/jira/browse/KAFKA-7599
Project: Kafka
Issue Type: Improvement
Reporter: Stanislav Kozlovski
Assignee: Stanislav Kozlovski
In Trogdor, the ConsumeBench, ProduceBench and RoundTrip workers all take in an
argument called "targetMessagesPerSec". That argument works as an upper bound
on the number of messages that can be consumed/produced per second in that
worker.
It is useful to support infinite messages per second. Currently, if the
`targetMessagesPerSec` field is not present in the request, the RoundTripWorker
will raise an exception, whereas the ConsumeBench and ProduceBench workers will
work as if they had `targetMessagesPerSec=10`.
I propose we allow for unbounded `targetMessagesPerSec` if the field is not
present.
Further, it would be very useful if some of these workers showed the
`messagesPerSecond` they have been producing/consuming at.
Even now, giving the worker a `targetMessagesPerSec` does not guarantee that
the worker will reach the needed `targetMessagesPerSec`. There is no easy way
of knowing how the worker performed - you have to subtract the status fields
`startedMs` and `doneMs` to get the total duration of the task, convert to
seconds and then divide that by the `maxMessages` field.
