TDUniqueEvent Used to describe the first event.
The server uses the event name and #first_check_id to determine if the event was first fired
If the event already exists in the system, the current data is ignored.
By default, the device ID is used as #first_check_id.
Overridden event that corresponds to the ta_overwrite operation.
Create the TDOverWritableEvent object to override the previous event data.
Passing eventId specifies the event that needs to be overridden.
Events that can be updated. Corresponds to the track_update operation.
In some scenarios, attributes in the event table need to be updated. You can create a TDUpdatableEvent and pass in an eventId identifying this data point.
Upon receiving such a request, the server uses the current attribute to override the previous attribute of the same name in the corresponding data of the eventId.
