Crate.io has announced an upgrade to its open source CrateDB, and introduced a commercial version. The database now is available as a managed service as well. CrateDB 2.0 features clustering enhancements and SQL improvements. The enterprise edition adds authentication and authorization features for enhanced security, which are not provided in the open source version. It also includes performance-monitoring tools and support for user-defined query functions to enable more advanced in-database analytics, said Andy Ellicott, CMO at Crate.io.
