System Design: Real-time Module Communication and Overload Handling
Design a real-time system operating on a single machine, comprising two modules (e.g., a producer and a consumer) that require low-latency communication.
Requirements:
- Communication Mechanisms: Propose various communication mechanisms suitable for this scenario (e.g., in-process calls, threads with queues, Inter-Process Communication (IPC) methods like pipes, Unix domain sockets, or shared memory, or even network-based options like gRPC/HTTP on localhost). Justify your choice of mechanism(s) based on the system's constraints and requirements.
- Overload Handling: Describe strategies to prevent system collapse if one module becomes saturated and cannot keep pace with the other. Discuss techniques such as buffering, backpressure, load shedding (e.g., dropping packets/messages), and prioritization. Additionally, identify the key metrics and signals you would use to detect saturation and trigger these overload mitigation strategies.
