Sampling

Platform export uses ParentBased(TraceIdRatioBased) head sampling with a BatchSpanProcessor. Customer sampling is whatever your collectors send — Mydle does not invent dropped spans.

Platform sampler

For mydle-web and mydle-worker:

Sampler: ParentBased + TraceIdRatioBased (root ratio from env; default 1 when OTLP export is enabled).
Processor: BatchSpanProcessor with bounded queue and export timeout.
Fail-open: sampling / export issues never throw into business handlers.

Customer collectors

Your SDKs and collectors decide what reaches POST /api/traces/v1/otlp. Unsampled or never-exported work does not appear in Mydle. Ingest does not backfill missing children.

Limitations

Incomplete traces after head sampling are expected — not a product bug inventing siblings.
Platform sampling config does not rewrite customer OTLP payloads.
