Gin Anleitung Best Databases for Gin (2026)
Compare the best database solutions for Gin. We review PostgreSQL, MySQL, and managed databases with GORM and sqlx integration.
Gin applications work with various database libraries. We've evaluated managed databases that integrate well with Go's database/sql and popular ORMs.
Warum es wichtig ist
Go's database/sql provides a solid foundation. The right database choice affects connection pooling, query performance, and operational complexity.
Wichtige Überlegungen
GORM vs sqlx
GORM for ORM features. sqlx for SQL with struct mapping. database/sql for raw control.
Connection Pooling
database/sql has built-in pooling. Configure MaxOpenConns and MaxIdleConns appropriately.
Migrations
Use golang-migrate or GORM AutoMigrate. Run migrations in CI/CD or on startup.
PostgreSQL vs MySQL
Both work great with Go. PostgreSQL has better JSON support. Choose based on team experience.
Context Support
Use context-aware queries (*WithContext in GORM, sqlx.Context). Enables proper timeout handling.
