Distributed tracing — quick notes
| Concept | Detail |
|---|---|
| Purpose | Stitch one request's work across many services |
| Mechanism | A correlation id propagated across boundaries |
| Span | One unit of work in one service |
| Requirement | Every service must propagate the context |
- A gap in the trace = missing propagation, not a fast service.
- Tracing separates the service that reports a failure from the one that caused it.
- Sampling is coherent per operation — but a given transaction may be absent.
