// A set of (label, value) pairs which were dropped during aggregation, attached
// to google.api.Distribution.Exemplars in google.api.Distribution values during
// aggregation.
//
// These values are used in combination with the label values that remain on the
// aggregated Distribution timeseries to construct the full label set for the
// exemplar values.  The resulting full label set may be used to identify the
// specific task/job/instance (for example) which may be contributing to a
// long-tail, while allowing the storage savings of only storing aggregated
// distribution values for a large group.
//
// Note that there are no guarantees on ordering of the labels from
// exemplar-to-exemplar and from distribution-to-distribution in the same
// stream, and there may be duplicates.  It is up to clients to resolve any
// ambiguities.
