Subject: Re: memory requirement for kafka - how to estimate

I'm not sure if anyone can give you exact numbers, but I think you'll find
Kafka brokers very light.  We run them on .... I think medium EC2 instances
and Kafka brokers they put hardly any strain on them.  If it helps give you
an idea, go to and look for "SA.Prod.Kafka".
 That's one of our Kafka "clusters".  You'll see how many messages this
processes, what their size is, a bunch of other metrics, and then the JVM
Memory info, which I hope gives you some idea of the footprint.
