How to create a topic

Apache Pulsar is a distributed messaging system that supports high performance and low latency. Topics are the primary way to structure data in Apache Pulsar. A Pulsar topic is a unit of storage that organizes messages into a stream. Each message in a topic has an offset, which uniquely identifies the message within the topic.
