1. HLD and LLD of Rate Limiter

Question

Accepted Answer

Rate Limiter is a software component used to control the rate of traffic sent or received by a system.

High-Level Design (HLD) of Rate Limiter involves defining the overall architecture and components of the system.
Low-Level Design (LLD) of Rate Limiter focuses on the detailed design of individual components, algorithms, and data structures.
Example: HLD may include defining the overall flow of requests through the rate limiter, while LLD may involve designing the specific data structures used for tracking request rates.
Example: HLD may involve deciding on the overall strategy for rate limiting (e.g., token bucket algorithm), while LLD may involve implementing the specific logic for updating and checking token counts.
