What is message processor?

A message processor is a software component or system that handles the receipt, processing, and routing of messages. It's a crucial element in asynchronous communication patterns, often used in distributed systems, microservices architectures, and enterprise integration scenarios. Message processors typically perform tasks such as message validation, transformation, enrichment, and routing based on predefined rules or policies. Common examples include message queues (like RabbitMQ or Kafka), message brokers, and event-driven architectures where components react to messages or events published by other components.
