(This information has been superseded by a newer design with an updated API)
The “database” built into JET/Hub is set up as a general-purpose key-value store - i.e. persistent data storage which can’t store or retrieve anything other than (arbitrary) data by key. Whereby the keys are treated as a hierarchical structure separated by forward slashes (“/”). This database looks very much like an ordinary file system, and also very much like an MQTT topics hierarchy.
