Building Real-Time Feature Pipelines
summary
Shows an end-to-end JavaScript pipeline that consumes Kafka events in Node.js, computes windowed, idempotent features, caches them in Redis with sensible TTLs for submillisecond reads, and pushes deltas via websockets; claims client-side ML with TensorFlow.js edge inference cuts latency and serving cost. Describes multi-layer caching (browser memory, regional Redis, CDN/edge), tracks P50/P95/P99 latency plus cache hit ratio and skew, and recommends an implementation roadmap: offline cache → Kafka streaming → small on-device models.
