Competitive advantages

CrateDB is typically used in operational analytics applications.

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 in order to monitor, predict and optimize the behavior of smart systems in real time.

Popular use cases include:
