CrateDB is a distributed SQL database that makes it simple to store and analyze large amounts of machine data in real time. CrateDB offers the scalability and flexibility typically associated with NoSQL databases, and the smallest CrateDB clusters can easily ingest tens of thousands of records per second. These data can be queried in real time, temporarily, and in parallel across the entire cluster.

CrateDB 5.1.2 is officially released, and the updated content of this version is as follows:
