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 benefits of an SQL database and the scalability and flexibility typically associated with NoSQL databases. Modest CrateDB clusters can ingest tens of thousands of records per second without breaking a sweat. You can run ad-hoc queries using standard SQL. CrateDB's blazing-fast distributed query execution engine parallelizes query workloads across the whole cluster.

CrateDB is well suited to containerization, can be scaled horizontally using ephemeral virtual machines (e.g., Kubernetes, AWS, and Azure) with no shared state. You can deploy and run CrateDB on any sort of network

from personal computers to multi-region hybrid clouds and the edge.

Features

  • Use standard SQL via the PostgreSQL wire protocol or an HTTP API.
  • Dynamic table schemas and queryable objects provide document-oriented features in addition to the relational features of SQL.
  • Support for time-series data, realtime full-text search, geospatial data types and search capabilities.
  • 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.
