Problem Statement
Design the backend system for an LLM-powered chat product tailored for customers in a financial-technology environment. While a simple chat UI demo will be provided for context, the scope of this design challenge is strictly the backend architecture.
Core Functionality
The system must robustly support the following features:
- Real-time Chat Interaction: Users must be able to send chat messages and receive streamed responses from the assistant.
- Conversation Management: The system needs to maintain and manage conversation history and context effectively for ongoing interactions.
- Multi-Agent Orchestration: Implement a sophisticated orchestration layer capable of managing multiple specialized agents. These agents may be responsible for distinct tasks such as planning, information retrieval, complex calculations, compliance checks, and generating the final user-facing response.
- Tool Integration: The system must facilitate secure and reliable calls to various internal services and external APIs as part of agent operations.
Non-Functional Requirements
The design must inherently address:
- Reliability: Ensure high availability and fault tolerance.
- Observability: Provide comprehensive monitoring, logging, and tracing capabilities.
- Data Security: Implement robust mechanisms for the safe and compliant handling of sensitive financial data.
Deliverables
Your design should cover:
- The overall system architecture.
- Identification of main services and their responsibilities.
- The data model for critical entities.
- A detailed request flow for a typical user interaction.
- A comprehensive scaling strategy.
- Strategies for failure handling and recovery.
