흔히 이렇게 알고 있다

ParentBased(NeverSample()) disables span sampling across all spans created by the TracerProvider

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• ParentBased(NeverSample()) samples and exports child spans when the context contains a sampled remote parent, because ParentBased delegates sampled remote parents to AlwaysSample() by default rather than the configured root sampler.
• ParentBased(AlwaysSample()) drops and suppresses child spans when the context contains an unsampled remote or local parent, because ParentBased delegates unsampled parents to NeverSample() by default.
• Only root spans without a valid parent context evaluate the root sampler passed to ParentBased.
• ParentBased.Description() returns a composite string reflecting the root sampler and all four default sub-samplers.
