EventStreamQueryModelProfile
Aggregated domain event streams: one record per command, typed event payloads under body[].body.
Properties
When the record last changed: the default orderBy of FIRST and LAST metrics; null when there is none.
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.
Field that names the payload type of each record, or null when the payload is monomorphic.
Fields that every record of this model carries, independent of the aggregate.
The element whose variants are typed payloads (an event stream's body), or null for a monomorphic payload.
