QueryDatasets

class QueryDatasets(datasets: Collection<QueryDataset> = emptyList())

The datasets this instance serves, by name. Datasets join and leave at run time (dataset platform design §4.3): declaration files at startup, a registry's published versions afterwards. Reads take no lock; changes are serialized and reach every listener before the next one starts.

val all: Collection<QueryDataset>

schemaSource

val schemaSource: QuerySchemaSource

The schema source of the datasets' fields: a dataset's declaration is the base of its model, as inference is for an aggregate's, and other sources (a declaration file, a bean) may enrich it at a higher priority.
