Multiple instances of kafka producer

I understand that multiple instances of a producer application can be started to produce data to a topic. What configuration changes are required for this? Do i need different client_id? Without any changes , it works. So not sure if there are any benefit of changing client id or any other config param? Thanks,

The client id is simply used for logging on the server.

The purpose of this is to be able to track the source of requests beyond just ip/port by allowing a logical application name to be included in server-side request logging.

So it's not very important unless you have many producers in the same application.

To get a different client id for each producer, you would need a producer factory for each.

On the consumer side, you can specify a client id at the container (or @KafkaListener) level.
