Unless you are using some containerized implementation setting more than one broker on a server is likely going defeat some of the benefit Kafka brings with how it leverages page cache (more on that here https://kafka.apache.org/documentation.html#maximizingefficiency). You also need to think about competing for the disk usage too.
If this is just for testing development then having more than 3 brokers allows you to play with more failure and operation maintenance https://kafka.apache.org/documentation.html#basic_ops scenarios (especially if you set replication=3). /******************************************* Joe Stein Founder, Principal Consultant Big Data Open Source Security LLC http://www.stealth.ly Twitter: @allthingshadoop <http://www.twitter.com/allthingshadoop> ********************************************/ On Fri, Nov 28, 2014 at 12:24 PM, Sa Li <sal...@gmail.com> wrote: > Dear all > > I am provision production kafka cluster, which has 3 servers, I am > wondering how many brokers I should set for each servers, I set 3 brokers > in dev clusters, but I really don't what is the advantages to set more than > 1 broker for each server, what about 1 broker for each server, totally 3 > brokers, instead of 9 brokers. > > thanks > > > -- > > Alec Li >
