Generate naturally varying time intervals to improve realism in games and to prevent thundering herds in distributed systems

A cache module for node.js that uses a two-level cache (in-memory cache for recently accessed data plus Redis for distributed caching) with some extra features to avoid cache stampedes and thundering herds.

Ultra-fast in-memory request deduplication and TTL edge caching for Groq, OpenAI, Anthropic, and LLM APIs. Eliminates thundering herds and 429 rate limit spikes.

Cache Thundering Herds

A TypeScript utility that solves the Thundering Herd Problem by deduplicating concurrent operations

Three-tier Node.js cache: L1 smart RAM (adaptive LFU/LRU + Count-Min Sketch) → L1.5 NVMe disk spill → L2 Redis/Valkey. Includes AES-256-GCM at-rest encryption, WASM Bloom filter, Stale-While-Revalidate, and thundering-herd prevention.

A lightweight request-collapsing mechanism to prevent cache stampedes and thundering herd problems in Node.js.
