Specific characteristics

CrateDB is an open source distributed SQL database that spreads data and processing across an elastic cluster of identical, shared-nothing nodes.

  • Data is processed by append-only Lucene-based shards, with in-memory columnar field caches for fast query performance. 
  • CrateDB is a strong fit for query-intensive operational analytics workloads. It is not generally used for update-intensive OLTP workloads. 
  • The Lucene DNA in CrateDB enables dynamic schemas, text search, and rich JSON data handling in SQL

CrateDB's unique, distributed SQL-on-Lucene architecture makes it easy and economical for mainstream SQL developers to handle extreme analytic data requirements:

  • Scale to ingest millions of data points per second
  • Handle a variety of complex data structures - tabular, nested objects (JSON), BLOBs
  • Query data in real time, as it streams in--time series, text search, geospatial, AI analytics

Until recently, workloads like these necessitated a NoSQL solution like Cassandra, Elasticsearch, Splunk, or InfluxDB. CrateDB makes it possible to handle them without sacrificing the familiarity and power of SQL

Read the CrateDB Technical Overview

Competitive advantages

CrateDB is typically used in operational analytics applications, particularly those that process machine-generated data.

In those scenarios, CrateDB competitive advantages include:

  • Easier to adopt and integrate than proprietary NoSQL DB interfaces - SQL!
  • Query versatility - SQL joins, aggregations, special indexing for time series, text search, geospatial, user-defined functions for AI/ML
  • Simple scaling and high availability - CrateDB automates partitioning, sharding, replication, indexing.
  • Real-time performance - ingests and queries data in real-time via parallel processing, in-memory columnar indexes.
  • Dynamic schemas - new columns and nested object (JSON) attributes are added to the schema automatically as they are inserted.

Typical application scenarios

CrateDB is ideal for integrating and analyzing streams of data--often machine-generated--in order to monitor, predict and optimize the behavior of smart systems in real time.

Over 70% of CrateDB users surveyed use CrateDB to manage machine-generated data. Popular use cases include:

Key customers
