Netflix Druid caching is a solid infrastructure case study but not agent-focused.
Summary
Netflix's interval-aware caching for Apache Druid serves 84% of query results from cache by decomposing rolling window queries into granularity-aligned buckets with exponential TTL, reusing historical segments via an external proxy layer while recomputing only the most recent interval. This reduced query load by 33%, improved P90 latency by 66%, and cut result bytes up to 14x for real-time analytics dashboards processing trillions of rows.
