QueryDatasetProvider
A dataset backend (the ClickHouse one, say): the QueryBindings of the datasets it serves, opened from its settings and the application's resources. The host finds it with ServiceLoader (META-INF/services) and opens the one that is available; with several it refuses the start, naming them, and an application's own QueryBindings<QueryDataset> bean takes the place of any.
Properties
Every setting it reads from its QueryDatasetConfig.options, each read through its option, for the host to bind and check (wow.<type>.<key>); a dataset backend has no instances of its own, so it reads a ProviderOption.Scope.PER_STORE option as one of its type.
Functions
Whether config lets it serve datasets: its resources are there and its settings do not switch it off.
The bindings of the datasets it serves, over config. Bindings that hold resources of their own, a client the provider opened say, are AutoCloseable: the host closes them when the node stops. What they use of the application's resources they never close.
