TraceExporter	Potentially exports a trace to an underlying consumer.

Class Summary

Class	Description
LoggingTraceExporter	Trace exporter which dumps traces and their description as warning-entries in the Vespa log.
MaxSamplesPerPeriod	Very basic sampling strategy which allows for sampling N requests within a fixed time window.
ProbabilisticSampleRate	Simple implementation of OpenCensus algorithm for probabilistic rate limiting as outlined in https://github.com/census-instrumentation/opencensus-specs/blob/master/trace/Sampling.md
SamplingTraceExporter	Trace exporter which only exports a subset of traces as decided by the provided sampling strategy.
TraceDescription	High-level description of a trace and the actual trace itself.
