It involves several features and architectural changes: + * **Shared sampling state**: the sampling state is shared across all local + (i.e. in-process) spans for a given trace. + * **New `SamplerV2` API** allows the sampler to be called at multiple points + in the life cycle of a span: + * on span creation + * on overwriting span operation name + * on setting span tags + * on finishing the span + * **Final/non-final sampling state**: the new `SamplerV2` API allows the sampler + to indicate if the negative sampling decision is final or not (positive sampling + decisions are always final). If the decision is not final, the sampler will be + called again on further span life cycle events, like setting tags. + +These new features are used in the experimental `x.TagMatchingSampler`, which +can sample a trace based on a certain tag added to the root +span or one of its local (in-process) children. The sampler can be used with +another experimental `x.PrioritySampler` that allows multiple samplers to try +to make a sampling decision, in a certain priority order. + ### Baggage Injection The OpenTracing spec allows for [baggage][baggage], which are key value pairs that are added |
