The Scalable SQL Database for Machine Data
CrateDB is the leading open-source, distributed SQL database for relational and time-series data
A Unique Machine Data Experience
CrateDB is purpose-built for the need to scale volume, variety and velocity of data while running aggregated complex real-time queries, anywhere and without driving up costs
Variety
Readily handle structured and unstructured data, regardless of data shape
Real-time
Run ad hoc queries in real-time - no waiting necessary
Run anywhere & everywhere
Run on-premise or in the cloud, any cloud
Aggregation
Condense and distill to get what you need and when you need it
Simple scalability
Unique architecture that’s simple to scale and keeps running 24/7 with no bottlenecks
SQL & NoSQL
Index high data volumes with a distributed SQL DBMS built atop NoSQL storage
PostgreSQL
Use standard SQL without the need to learn new skills
CrateDB is data-shape agnostic
Ready to handle structured and unstructured data
