CrateDB
Distributed SQL database for real-time analytics at any scale
About CrateDB
CrateDB is a distributed SQL database engineered for real-time analytics on high-velocity data streams. It combines fast ingestion with millisecond query latency, handling complex aggregations, joins, hybrid search, and AI feature queries across time-series, JSON, geospatial, and vector data types in a unified SQL engine. Designed for enterprises managing massive volumes of machine-generated data from IoT sensors to application logs.
