⚡ Bolt: optimize rate limiter Redis round-trips#215
Conversation
Reduced Redis network round-trips in \`SlidingWindowRateLimiter.consume\` from 2 to 1 for successful requests and from 3 to 2 for denied requests by consolidating the \`zrange\` call into the initial pipeline. 💡 What: Included \`zrange\` in the initial pipeline to fetch the oldest member's score. 🎯 Why: Minimizing network round-trips is critical for the API Gateway as it runs rate limiting on every request. 📊 Impact: Reduces rate limiting latency by ~50% for successful requests and ~33% for denied requests (excluding Redis execution time). 🔬 Measurement: Verified via \`packages/cache/src/index.test.ts\` counting mocked Redis calls.
