Deep Dive into Pulsar Lifecycle

In Pulsar, topics carry messages sent by users. When a message is sent to a topic, it will be calculated by broker and then stored in bookie. In this talk, we will elaborate on how the message is sent to the broker and finally stored in bookie after the broker's calculation and metadata processing. Then we will explain how Bookie uses the garbage collection(GC) mechanism to recycle the data in the topic, and how the TTL and retention policies in the broker act on the Bookie Client to trigger the garbage collection mechanism.
