A multi-agent system is a team of specialized agents working together to solve complex problems. In the context of meal planning, this means combining multiple agents to create a cohesive plan that caters to various preferences and dietary needs. The system uses event-driven architecture, with Apache Kafka as the backbone for communication between agents, and tools like Apache Flink and LangChain for processing and generating outputs. Each agent operates independently but collaborates through events to achieve a common goal. This approach simplifies complex tasks by breaking them down into manageable components and enables scalability, flexibility, and fault isolation. The system can be extended or modified as needed, making it suitable for various domains beyond meal planning.
