Doctrine Fetch Modes (Symfony)

Use when

  • Designing entity relations or schema evolution.
  • Improving Doctrine correctness/performance.

Default workflow

  1. Model ownership/cardinality and transactional boundaries.
  2. Apply mapping/schema changes with migration safety.
  3. Tune fetch/query behavior for hot paths.
  4. Verify lifecycle behavior with targeted tests.

Guardrails

  • Keep owning/inverse sides coherent.
  • Avoid destructive migration jumps in one release.
  • Eliminate accidental N+1 and over-fetching.

Progressive disclosure

  • Use this file for execution posture and risk controls.
  • Open references when deep implementation details are needed.

Output contract

  • Entity/migration changes.
  • Integrity and performance decisions.
  • Validation outcomes and rollback notes.
