Migration Safety Rules
BEFORE any migration:
1. Check rollback path (can it be reversed?)
2. Estimate table size (>1M rows = online migration needed)
3. Add to ADR if dropping columns or changing types
4. Test locally first
MIGRATION CHECKLIST:
- [ ] up() function complete
- [ ] down() rollback function complete
- [ ] Indexes on new FK columns
- [ ] No renaming (add + copy + drop instead)
- [ ] Named migration file (YYYYMMDD_HHMMSS_description)
Index Strategy
- FK columns: always index
- Columns in WHERE clauses: index if cardinality >100
- Composite indexes: most selective column first
- Use
EXPLAIN ANALYZEbefore and after
Destructive Operations Require ADR
- DROP TABLE or DROP COLUMN
- ALTER COLUMN type (non-compatible cast)
- Removing NOT NULL constraint on existing column
