Producing messages randomly over partitions

I don't set key while sending messages. Do I have guarantees that messages will go to partititions randomly ? If not how can I achieve this ? I want be sure that my consumers (in one cusumer group) will be evenly loaded.

Without a key, your Kafka Producer will - by default - apply a RoundRobinPartitioner which will distribute the messages accross the partitions evenly.

If you are looking for a pure "random" Partitioner you could write a custom Partitioner that assigns a partition randomly.
