FAQPage Schema

How do I handle Drizzle migrations when tightening constraints in production?▼

Drizzle migrations for constraint changes require a backfill-first workflow: generate and apply data backfills before tightening constraints, reducing downtime and risk in evolving production schemas.

What is the safest way to backfill data before a schema migration?▼

The safest way to backfill data is to sequence backfills before schema migrations, using automated generation commands like bun run db:generate for both backfills and schema changes, then verify against drizzle/meta/_journal.json.

How do I verify Drizzle migration snapshots before deploying to production?▼

Verify Drizzle migration snapshots by checking drizzle/meta/_journal.json and migration snapshots after running automated generation commands, ensuring backfill-first sequencing and documented deployment decisions.

Can I use bun run db:generate for both backfills and schema migrations?▼

Yes, bun run db:generate is used for both backfills and schema migrations in a coordinated workflow that enforces backfill-first sequencing and requires verification against drizzle/meta/_journal.json and migration snapshots.

Does this Drizzle migration workflow include rollback planning?▼

Yes, the Drizzle migration workflow includes deployment planning and rollback guidance with documented decisions and checklists for production environments with evolving schemas.

When should I not use a backfill-first migration approach?▼

A backfill-first migration approach may not be necessary for simple additive schema changes that do not involve constraint tightening or data transformations in production environments.
