CrateDB

CrateDB is a distributed SQL database built for real-time analytics, search, and AI applications at any scale.

Description

CrateDB is a distributed, real-time analytics database designed for high-performance processing of fast-moving data at any scale. It enables organizations to ingest high-velocity data streams and make them queryable within milliseconds, supporting real-time dashboards and applications even with billions of records. The database excels at handling high-cardinality, multi-dimensional data without performance degradation, allowing detailed analysis across various dimensions like devices, customers, or regions. CrateDB unifies analytics, full-text search, and semantic search in a single distributed SQL engine, eliminating the need for complex data pipelines between different systems. It maintains SQL as its core query language for all data types including time series, JSON, geospatial, text, relational, and vector data, making it accessible to teams with SQL knowledge. The platform is built for operational simplicity with automatic indexing, built-in replication, and shared read/write nodes that deliver predictable performance without constant tuning.

Features

• Distributed SQL engine for real-time analytics with millisecond query response times
