What issue do you find in Pulsar docs?

It is written that using namespace change events :

• Avoid using ZooKeeper and introduce more loads to ZooKeeper.

https://pulsar.apache.org/docs/4.0.x/concepts-multi-tenancy/#namespace-change-events-and-topic-level-policies

I don't understand the purpose of this : is it use more or less Zookeeper ?

I agree, it's hard to understand. There's a need to improve this description. My assumption is what it means is that namespace change events (and topic level policies) provide a way to reduce load on the metadata store backend (which is Zookeeper in most cases with Pulsar).
