Flags can be used to control how features are added to the sink. For now, there's only a single flag available - FastInsert. When FastInsert is set, faster inserts will be use at the cost of updating the passed features to reflect changes made at the provider. This includes skipping the update of the passed feature IDs to match the resulting feature IDs for the feature within the data provider. Individual sink subclasses may or may not choose to respect this flag, depending on whether or not skipping this update represents a significant speed boost for the operation. QgsVectorLayer always ignores the flag - feature ids are required for the featureAdded signal to be correctly emitted, and it's expected that performance critical applications will add features directly to a data provider instead of via QgsVectorLayer's edit buffer.
