Overview

Package migrations handles database schema migrations with version tracking.

Migration System:

  • Each migration has a unique version number
  • schema_version table tracks applied migrations
  • Migrations run in transaction (all-or-nothing)
  • Bootstrap migration detects pre-existing databases

Adding New Migration:

  1. Create file XXX_descriptive_name.go (XXX = next version number)
  2. Register migration in init() using migrations.Register()
  3. Implement up(tx) function with schema changes
  4. Add verification test in runner_test.go
