Reference documentation and code samples for the Discovery Engine v1 API class Control.Types.BoostAction.Types.InterpolationBoostSpec.Types.ControlPoint.
The control points used to define the curve. The curve defined
through these control points can only be monotonically increasing
or decreasing(constant values are acceptable).
The duration spec for freshness:
The value must be formatted as an XSD dayTimeDuration value (a
restricted subset of an ISO 8601 duration value). The pattern for
this is: [nD][T[nH][nM][nS]].
