Sampling
Head sampling is a sampling technique used to make a sampling decision as early as possible. A decision to sample or drop a span or trace is not made by inspecting the trace as a whole. For example, the most common form of head sampling is Consistent Probability Sampling. This is also be referred to as Deterministic Sampling.
