It captures 4 rate-limit definitions, measuring unit, varies, and none.

Policies

Backoff Strategy
Honor 429 responses with exponential backoff and jitter; SDKs handle retry automatically.
Trace Batching
SDKs batch trace ingestion calls before flushing, reducing per-request overhead.
OpenTelemetry Path
Use the OTel ingestion endpoint where possible; it is the recommended, higher-throughput path.
