Represents an embedded object in an update. This is a wrapper class that can contain a single specific item proto in an extension field. Think of it as a base class like Message in Java. Each item proto must declare that it extends this proto: message ExampleObject { option (item_type) = EXAMPLE_OBJECT; extend EmbedClientItem { optional ExampleObject example_object = ; } } See go/es-embeds for details.

This field records where the ItemScope was retrieved, if it was created via a web fetch.

An EventId is a 128 bit identifier that uniquely identifies an event, such as a query. The event time recorded to the nearest microsecond, along with information about the process generating the event, ensures that all EventIds are unique. Details of this EventId are described in a design document: http://www/eng/designdocs/sawmill/adlogs.html
