Overview ¶
Package trace encapsulates a module which contains the entirety of the trace-agent's processing pipeline. The code may be reused to process traces in the same way that the Datadog Agent does, but outside of it.
Please note that the API is subject to major changes and should not be relied upon as being stable.

Package sampler contains all the logic of the agent-side trace sampling Currently implementation is based on the scoring of the "signature" of each trace Based on the score, we get a sample rate to apply to the given trace Current score implementation is super-simple, it is a counter with polynomial decay per signature.
