Krypton: Real-time Serving and Analytical SQL Engine at ByteDance

Summary: Krypton: cloud-native HSAP unifying real-time serving and ad‑hoc OLAP to avoid multi-system ETL, supporting high freshness, ingestion rates and strong consistency. Leverages hierarchical persistent‑memory cache, native columnar storage and optimized query processing for elastic, low‑latency complex queries. (summarized by gpt-5-mini on Feb 09 2026)
