Chickenzilla opened a new issue #7896: URL: https://github.com/apache/pulsar/issues/7896
**Is your enhancement request related to a problem? Please describe.** We are trying to validate performance characteristics in a key-shared subscription scenario, but when configuring pulsar-perf to send/consume from a given topic using key-shared, only one consumer on the topic receives all of the messages. This is unrealistic and not a good validation of expected typical key-shared functionality. **Describe the solution you'd like** A command line switch should be added to allow setting the message's routing key to either a random or incrementing value, such that multiple key-shared consumers will spread the load somewhat evenly, while keeping overhead of production low. **Describe alternatives you've considered** Short of writing/using our own performance tool, there is no alternative or workaround. In order for key-shared consumers to share, they must receive messages published in a way that allows for it. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
