DatasetQueryModelProfile
The record layout of one dataset: the whole record is payload, so fields and masks live at the root; the system fields are the dataset's own columns, and one it does not declare (an aggregate id, a deletion flag) is not carried. A dataset has no default scope: what a record's lifecycle means belongs to the dataset.
Properties
When the record last changed: the default orderBy of FIRST and LAST metrics; null when there is none.
The one tenant every record belongs to, for a model with no tenant field (a platform-level dataset); null otherwise. A tenant filter then matches every record when it names this tenant and none when it names another, and it pins requiredScope.
Unique record identity: the target of id filters and the tie-breaker of every cursor; null when the model declares none, which rejects both.
Logical field that holds the user payload; masked fields and schema extensions must live below it. null when the whole record is payload, as in a dataset.
The tenant column, or, for a platform-level dataset, the tenant it pins through fixedTenantId.
None: a dataset's fields are its declaration, supplied by QueryDatasets as a schema source.
The column each ABAC tag key is bound to; empty when the dataset takes no part in ABAC.
Functions
The logical field a system-field filter (ID, TENANT_ID, DELETION, ...) targets: identityField for the record identity; null when the model does not carry field.
