Question 1

Does Migrator support down migrations or rollbacks?

Accepted Answer

No, Migrator follows an append-only philosophy and does not support down migrations. Instead, it encourages adding new corrective migrations, which means you must write additional code to fix issues rather than rolling back changes directly.

Question 2

How to use Migrator with MySQL in a Go project?

Accepted Answer

Use a MySQL driver compatible with database/sql, such as go-sql-driver/mysql, and pass the connection to migrator.New. Ensure migration names are SQL-safe for MySQL, escaping characters like single quotes manually as described in the README.

Question 3

Migrator vs golang-migrate for Go database migrations?

Accepted Answer

Migrator is lighter and supports Go code migrations with transactional flexibility, but lacks down migrations and CLI tools. golang-migrate is more feature-rich with SQL support and a CLI, but doesn't allow Go code migrations, making Migrator better for complex logic embedding.

Question 4

Can I use Migrator with SQLite databases?

Accepted Answer

Yes, if SQLite has a driver compatible with Go's database/sql package, but it's not explicitly tested. You might encounter issues since the README only guarantees PostgreSQL and MySQL, so proceed with caution and contribute fixes if needed.

Question 5

How to handle migration failures with Migrator's append-only approach?

Accepted Answer

Since down migrations aren't supported, you must write a new migration to correct errors or manually intervene in the database. The README suggests this philosophy avoids complexity but requires careful planning for failure scenarios.

Question 6

Is Migrator suitable for large teams with multiple developers?

Accepted Answer

It can work, but the lack of built-in version tracking and rollback features might complicate collaboration. Teams would need to establish strict processes for migration ordering and error handling, as the library provides minimal oversight tools.
