StarRocks

StarRocks is a high-performance analytical database designed for real-time analytics, supporting both real-time and lakehouse querying. Its architecture enables sub-second latency for complex, multi-table queries at scale without requiring data denormalization or copying. Built on open formats and standards, StarRocks allows direct analytics on data residing in data lakes. It excels in serving AI agents with low latency and high concurrency, even with unoptimized SQL. Key use cases include real-time risk engineering (as demonstrated by DiDi), faster analytics at Pinterest, and query performance optimization at Shopee. The system provides a unified OLAP solution covering various data analytics scenarios and can handle second-level data updates and deletes without impacting query performance.
