EdgeDB 迁移与类型安全查询(2025)
一、模式与迁移
- Schema:定义类型/链接/属性与约束,避免隐式关系。
- 迁移:生成与应用迁移脚本;在环境中按序升级,保持一致性。
- 兼容变更:优先非破坏性变更(增加可空字段/默认值)。
二、类型安全查询
- 查询语言:EdgeQL 提供强类型;编译期校验减少运行时错误。
- 绑定:客户端 SDK 提供类型绑定与推断,简化开发。
- 视图与复用:以视图封装复杂查询,实现复用与治理。
三、事务与一致性
- 事务:将相关写操作置于同一事务;失败回滚。
- 约束:唯一性/外键/校验保证数据质量;避免跨事务不一致。
- 事件:触发器或规则在变更时执行审计与派发。
四、性能与观测
- 索引:针对高选择性字段建立索引;避免过度索引。
- 观测:记录查询延迟与资源占用;基线对比优化。
- 安全:最小权限访问与密钥治理。
注意事项
- 关键词(EdgeDB、迁移、类型安全、查询、Schema)与正文对应。
- 分类为“数据库/EdgeDB/模式”,不超过三级。
- 参数与策略需在预生产演练与回归验证。
