Data interoperability

CrateDB offers data collection and storage for any type of data source: sensor data, historical data, geospatial data, operational parameters, environmental conditions ...

You can store complex objects in the database, before even knowing how you want to model your data. You can also add new data types and formats on the fly, thanks to dynamic schema capabilities. There is no need for human intervention and no need to synchronize multiple databases.

Scalability and performance

With CrateDB, data is available for query instantly after data ingestion. You get response-time in milliseconds - even for complex ad-hoc queries across billions of records - thanks to a fully distributed query engine. This gives you real-time insights and responsiveness.

CrateDB computes data aggregations on the fly thanks to columnar storage. There is no need to downsample or pre-aggregate the data.

To meet the stringent requirements of industrial environments, CrateDB can scale easily. This way, you can cope with the huge volumes of IoT data continuously flowing from different sources.

Time-series

CrateDB has all the features of an advanced time-series database. This includes instant access to years of data, thanks to a distributed architecture with efficient sharding and partitioning mechanisms.

CrateDB also provides efficient storage, and instant querying of time stamped data to enable trend analysis, forecasting, and historical comparisons.

Fault tolerance built-in
