1. `RateLimitingSampler` can be used to allow only a certain fixed
number of traces to be sampled per second.
#### Delayed sampling
Version 2.20 introduced the ability to delay sampling decisions in the life cycle
of the root span. 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
