Hi Adrien, Without asking the author directly I can't give the exact answer but I would interpret that as per broker. Kafka will make use of as much hardware as you give it so it's not uncommon to see many CPU cores and lots or RAM per broker. That being said it's completely down to your use case how much hardware you would require.

Or 24 GB for example for each broker ? Thank you very much, and best regards, Adrien Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
