About

CrateDB is a distributed SQL database that makes it simple to store and analyze massive amounts of machine data in real-time.

CrateDB offers the scalability and flexibility typically associated with a NoSQL database, is designed to run on inexpensive commodity servers and can be deployed and run on any sort of network - from personal computers to multi-region hybrid clouds.

The smallest CrateDB clusters can easily ingest tens of thousands of records per second. The data can be queried, ad-hoc, in parallel across the whole cluster in real time.

Features

  • Standard SQL interface available via HTTP API and PostgreSQL wire protocol.

  • Dynamic schemas, queryable objects, geospatial features, time series data support, and realtime full-text search providing functionality for handling both relational and document oriented nested data structures.

  • Horizontally scalable, highly available and fault tolerant clusters that run very well in virtualized and containerised environments.

  • Extremely fast distributed query execution.

  • Auto-partitioning, auto-sharding, and auto-replication.

  • Self-healing and auto-rebalancing.
