Separate zookeeper install or not using kafka 10.2?

Viewed 2979

I would like to use the embedded Zookeeper 3.4.9 that come with Kafka 10.2, and not install Zookeeper separately. Each Kafka broker will always have a 1:1 Zookeeper on localhost.

So if I have 5 brokers on hosts A, b, C, D and E, each with a single Kafka and Zookeeper instance running on them, then is it sufficient to just run the Zookeeper provided with Kafka?

What downsides or configuration limitations if any does the embedded 3.4.9 Zookeper have compared to the standalone version?
