Subject Knowing when to grow a Kafka cluster
Date Thu, 27 Dec 2018 00:17:10 GMT

Many articles exist about running Kafka at scale, but there are fewer
resources for learning when to grow your cluster (e.g. adding a new broker
or upgrading the computer it's running on).

At first, the answer to that seems straightforward - you add a broker if
you want to reduce the amount of network I/O, CPU utilization, etc. a
broker experiences. But when and how do you know a brokers are taxed too
heavily and it's time to add a new one? Any thoughts about scaling by
adding brokers vs. scaling with more powerful hardware?
