CrateDB is a distributed SQL database for real-time analytics on high-volume operational data. In a single SQL engine it handles time-series, JSON, full-text, vector, geospatial and relational data; sensor, streaming and log data can be queried immediately after ingestion. CrateDB has built-in replication, automatic failover and automatic sharding, and scales horizontally by adding nodes. Access is via the PostgreSQL wire protocol or a REST HTTP endpoint. You can run CrateDB yourself (on-premises, at the edge or in the cloud) or use it as a managed service through CrateDB Cloud.
The core is licensed under the Apache License 2.0; an OSS edition and an Enterprise edition exist for self-managed use. The developer is Crate.io, Inc., with an office in the United States and offices in Germany, Switzerland and Austria; the project began in Dornbirn. CrateDB Cloud is available through the AWS, Azure and GCP marketplaces; the documentation does not state which regions are offered. Self-hosting on European infrastructure gives you full control over where your data is located.
