Crate.io released CrateDB4.0 to allow IoT- and IIoT-fueled organizations to put their machine and sensor data to work. It is a distributed SQL database based on a NoSQL architecture that takes advantage of the convenience of SQL for processing any structured or unstructured data type. Dynamic schemas make it easy to add new data types or indexes, and the architecture allows horizontal scaling by interconnecting servers to capture millions of IoT and IIoT data inputs per second (totaling hundreds of terabytes in cluster size). Distributed processing, data partitioning, and in-memory indexes return millisecond responses to time-series requests — even when many clients are working in the database simultaneously.
