Commit sampling defaults while rare error traces remain at risk

You’re the software engineer. Your team is in the room. Printed Oct 13, 2026.

Ingestion relief is pulling against the trace evidence needed for rare failures.

Lower retained volume protects platform capacity while richer tail coverage protects engineers during outages.

Who you’d be doing this for

“The failures happen once in a while, and those are exactly the traces I need when leadership asks why.”

Shahram Demir · Site Reliability Engineer

Runs a high-volume distributed payments platform and investigates intermittent failures through retained traces.

What is at stake

Replay data shows the proposed default cuts ingestion but drops rare confirmed error paths. You have to weigh capacity relief against evidence engineers cannot recover after an incident.

Why it isn’t already fixed

Every obvious fix costs something else. That’s the part you’d have to decide.

  • capacity headroom vs incident evidence
  • uniform control vs request-aware sampling
  • automated replay labels vs verified incident truth
  • cross-language consistency vs rapid relief

Why Datadog

APM SDKs and the Event Platform jointly determine which customer request paths remain available for investigation at scale.
