high-concurrency-scalability

What problem does it solve?

High-concurrency systems face lock contention, tail latency, and brittle scaling under load. This skill provides a structured approach to selecting concurrency models, designing for backpressure, and planning capacity to sustain throughput and reliability across services.

Core Features & Use Cases

• Concurrency model selection (threads, async/await, actors) and lock-free patterns
• Backpressure, bulkheads, rate limiting, and capacity planning
• Horizontal scaling, read replicas, sharding, and CDN-edge considerations
• Observability and profiling guidance to identify bottlenecks and tune capacity

Quick Start

Provide a starter concurrency strategy for a high-traffic API and outline the steps to implement it.
