Best Practices

Schema Management

  1. Always compare schemas before deployment
  2. Test migrations in staging environment
  3. Document all changes in migration files
  4. Verify backward compatibility when possible
  5. Plan rollback strategy for every migration

Migration Safety

  1. Review migration critical report before every deployment
  2. Run migrations in transaction when possible
  3. Test rollback procedures before deployment
  4. Monitor performance impact during migration
  5. Have DBA on standby for critical migrations

Data Quality

  1. Regular verification of data integrity
  2. Automated quality checks in CI/CD
  3. Monitor data consistency across tables
  4. Document data quality issues and fixes
  5. Prevent issues through constraints and validation
