Worked on the dragonflyoss/dragonfly repository to enhance database migration reliability by addressing cross-dialect compatibility issues. Focused on backend development using Go and GORM, the work involved implementing a targeted fix to ensure that text types, including JSONMap and Array structures, are mapped correctly across PostgreSQL, MySQL, SQLite, and SQL Server. This adjustment reduced migration-time failures and minimized the need for manual intervention during deployments. By aligning type representations in the ORM layer, the changes improved the portability and maintainability of schema migrations, ensuring consistent data-type handling and supporting smoother upgrades across diverse database environments within the project.
