+ + +Modern cloud systems rarely fail because of code alone. +Most incidents happen when a **new environment boots incorrectly**, or when **database / schema migrations run at the wrong time**. + +When environments initialize out of order, migrations can race with services, schemas drift between regions, and agents read partially upgraded data. + +This page provides guardrails for safe environment bootstrap and predictable migration workflows in serverless and event-driven systems. + +--- + +## When to use this page + +* New deployments fail on the first request but work after retry. +* Database schema mismatches appear after a rollout. +* Services start before dependencies are ready. +* Jobs run migrations twice or skip them entirely. +* A new region or environment returns inconsistent responses. + +--- + +## Open these first + +* Boot order and deploy sequencing: + [Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) + +*

Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md) + +--- + +## Acceptance targets + +* Environment bootstrap completes without manual retries. +* Migrations execute exactly once per revision. +* Schema versions consistent across all regions. +* No service reads data from a partially migrated schema. +* Migration runtime predictable and observable. + +For RAG stacks: + +* ΔS(question, retrieved) drift ≤ 0.03 after reindex. +* Index metadata identical across environments before traffic. + +--- + +## Fix in 60 seconds + +1. **Separate bootstrap from service startup** + + Infrastructure initialization, secrets loading, and migrations should run before application services accept traffic. + +2. **Run migrations as a controlled job** + + Execute migrations through a dedicated job runner or CI pipeline rather than inside request handlers. + +3. **Version everything** + + Track `schema_rev`, `index_hash`, and `release_id`. + Services refuse to start if incompatible versions are detected. + +4. **Gate traffic after bootstrap** + + Block user traffic until health probes confirm: + + * schema ready + * secrets loaded + * index parity verified + +5. **Record migration state** + + Store migration history in a durable table so jobs cannot re-run completed migrations. + +--- + +## Patterns that work + +* **Migration job runner** + + Use a scheduled job or container task to execute migrations before service rollout. + +* **Immutable environment revisions** + + Each deploy produces a new revision with explicit schema and index versions. + +* **Schema compatibility windows** + + Design migrations so old services can still read during rollout. + +* **Bootstrap contract checks** + + Health probes validate schema version, secrets version, and index hash before allowing traffic. + +--- + +## Typical breakpoints → exact fix + +* **Service starts before migration finishes** + + Boot sequence incorrect. + Gate startup until migration completion. + + Open: + [Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) + +--- + +* **Migration runs twice** + + Retry job executes again
