Procella: Unifying serving and analytical data at YouTube

Summary: Procella unifies dashboards, embedded metrics, monitoring, and ad-hoc analytics in one SQL engine, replacing workload-specific silos. It serves fresh data at millisecond latency and high QPS while supporting complex queries over trillions of rows, reaching hundreds of billions of queries daily.
