Best Format for Database Seed Replay

SQL is the best default when replay accuracy, transactions, and schema-aware setup matter more than raw interchange simplicity.

Primary Recommendation

SQL (Data)

SQL preserves database-native operations like transactions, DDL, and ordered seed replay in a way flat exports cannot.

Fallback and Alternative Formats

CSV (Document)

Files: 21

Use CSV for tabular interchange where downstream loading rules are already defined.

JSON (Document)

Files: 19

Use JSON when nested structures and payload debugging matter more than SQL replay semantics.

SQLITE (Data)

Use SQLite snapshots when you need portable embedded state instead of text-based replay.

Decision Factors

  • Need for transactional replay versus flat data import.
  • Requirement to preserve schema changes, ordering, and rollback behavior.
  • Portability across toolchains versus database-native execution fidelity.
  • How often support or QA needs to inspect and diff the fixture by hand.

Common Mistakes to Avoid

  • Using CSV as the only seed artifact when ordered transactional replay is required.
  • Treating a large SQL fixture like a dummy blob instead of validating it against a real parser and database.
  • Skipping rollback rehearsal before promoting large seed loads into CI or staging.
