Here we simply distinguish:
Single-node single broker: On a single machine, a Kafka instance is launched (this is the model in the previous article).
Single-node multi-broker: Turn on multiple Kafka (pseudo-distributed like Hadoop) on the same machine.
Multi-node Multi-broker: Open multiple Kafka on multiple machines separately.
