type DataSource interface {
	// Observe queries the data source. Returns a value or an error. Once the
	// context is expires, Observe may still do cheap computations and return a
	// result, but should return as quickly as possible.
	//
	// More details: In the current implementation, the context passed to
	// Observe will time out after MaxDurationObservation. However, Observe
	// should *not* make any assumptions about context timeout behavior. Once
	// the context times out, Observe should prioritize returning as quickly as
	// possible, but may still perform fast computations to return a result
	// rather than error. For example, if Observe medianizes a number of data
	// sources, some of which already returned a result to Observe prior to the
	// context's expiry, Observe might still compute their median, and return it
	// instead of an error.
	//
	// Important: Observe should not perform any potentially time-consuming
	// actions like database access, once the context passed has expired.
