These are concepts used to interact with Kafka using the CLI, and come bundled with the Kafka binaries. Follow the quick start guide to install Kafka and get started, located here.

Important Notes 📝

• use the bootstrap server option EVERYWHERE.
  • i.e kafka-topics --bootstrap-server localhost:9092

  since zookeeper will be deprecated in the future

  • i.e kafka-topics --zookeeper localhost:2181 (don’t do this, this is bad)

• when running a command from the CLI and you get the following error

  Warn [AdminCLient clientId=adminclient-1] Connection to node -1
