Open source, hyper-fast and distributed database for all types of data - structured, semi-structured and unstructured - that combines the simplicity of SQL with the scalability of NoSQL.

Data-driven applications in today's world require fast response times, real-time insights, and constant improvement, which can be very challenging when integrating multiple data sources and databases together. CrateDB solves this problem by providing a unified representation for all types of data, enabling hyper-fast and scalable execution, and offering multiple deployment options.
