6,502عرض على GitHubpgroll is a PostgreSQL migration framework designed for zero-downtime schema changes. It applies non-blocking DDL operations that avoid exclusive locks on tables, and uses trigger-based column backfill to populate new columns while keeping them synchronized with old ones. The framework wraps each migration step in a database transaction that can be atomically committed or rolled back, and creates a versioned view layer that exposes both old and new schema versions simultaneously to client applications. The tool distinguishes itself by managing multiple schema versions via views, enabling safe
