Mastering the Thundering Herd Problem: Mitigations, Caching Strategies, and Production-Ready Patterns

This post walks engineers through the root causes of the thundering herd problem and shows concrete, production‑ready patterns—especially with Kafka and Redis—to keep latency low and resources stable.

Why the Memory Hierarchy Dictates Effective Access Time

A deep dive into why the structure of the memory hierarchy determines the real‑world latency of data accesses, illustrated with calculations and practical advice.
