public class BasePulsarConsumerInstrumentation
extends ClassInstanceMethodsEnhancePluginDefine

The pulsar consumer instrumentation use ConsumerImpl as an enhanced class. Consumer is a user-oriented interface and the implementations are ConsumerImpl and MultiTopicsConsumerImpl

The MultiTopicsConsumerImpl is a complex type with multiple ConsumerImpl to support uses receive messages from multiple topics. As each ConsumerImpl has it's own topic name and it is the initial unit of a single topic to receiving messages, so use ConsumerImpl as an enhanced class is an effective way.

Use messageProcessed as the enhanced method since pulsar consumer has multiple ways to receiving messages such as sync method, async method and listeners. Method messageProcessed is a basic unit of ConsumerImpl, no matter which way uses uses, messageProcessed will always record the message receiving.
