public TransactionOptions NewTransaction { get; set; }
Options for beginning a new transaction for this request.
The new transaction identifier will be returned in the corresponding
response as either
[LookupResponse.transaction][google.datastore.v1.LookupResponse.transaction]
or
[RunQueryResponse.transaction][google.datastore.v1.RunQueryResponse.transaction].
Reads entities as they were at the given time. This value is only
supported for Cloud Firestore in Datastore mode.
This must be a microsecond precision timestamp within the past one hour,
or if Point-in-Time Recovery is enabled, can additionally be a whole
minute timestamp within the past 7 days.
The identifier of the transaction in which to read. A
transaction identifier is returned by a call to
[Datastore.BeginTransaction][google.datastore.v1.Datastore.BeginTransaction].
