In some places on the page it says to use --zookeeper localhost:2181 as the argument to creating kafka topics. This should instead say --bootstrap-server localhost:9092

I'm assuming the zookeeper arg worked in previous releases, but the the latest confluent (7.3.3) it does not.

Kathryn Hancox (kathancox) commented: Hi Andrew Baptist , is this something you tested and ran into issues? Looking through the Zookeeper and Confluent documentation, Zookeeper seems to listen on {{2181}} still for the latest release with Kafka servers listening on {{9092}}.

Kathryn Hancox (kathancox) commented: It seems like Confluent 7.3.3 might not necessarily use ZooKeeper for managing its Kafka clusters. In newer versions, Confluent encourage users to use Kafka for storing metadata instead of ZooKeeper. (https://docs.confluent.io/platform/current/security/zk-security.html )

If you are using an older version of Confluent Platform that still relies on ZooKeeper, the default port for ZooKeeper bootstrap servers is 2181.

So, I think the change here is to update the newer changefeed examples to the recommended workflow.
