Audio N/AQuick interview answer
Debug Trunk-Based Development vs Long-Lived Branches by confirming blast radius, checking lag/error metrics, grabbing profiles/traces, then mitigating before deep root-cause. Simple view: Short-lived branches merge to main frequently; feature flags hide incomplete work. Long-lived release branches increase merge pain and drift.
Detailed answer
Production debug playbook for Trunk-Based Development vs Long-Lived Branches: 1) Stabilize: rate-limit, shed load, or roll back if users are hurting. 2) Orient: dashboards for latency, errors, saturation tied to Trunk-Based Development vs Long-Lived Branches. 3) Evidence: traces, profiles, logs with correlation IDs. 4) Hypothesize + prove with a safe experiment. 5) Fix + add a regression test/alert so it cannot silently return. Watch for: Week-long feature branches without syncing main. Parent context: Simple view: Short-lived branches merge to main frequently; feature flags hide incomplete work. Long-lived release branches increase merge pain and drift.
