Kylin4 Deployment and Performance Optimizations at Youzan

Since 2018 Youzan has migrated all online services to Kylin4, addressing long cube rebuilds, single‑point cache, CPU spikes, and throttling gaps by adding batch segment builds, low‑priority concurrency controls, Redis‑based query caching, parquet skew mitigation, range‑query acceleration, and class‑loader optimizations, which together doubled query‑per‑second capacity to 150, cut latency by up to 50 % and reduced CPU usage.
