Sparkdo.IdGeneration

Sparkdo.IdGeneration 提供 Sparkdo V 的默认 Id 生成运行时：UUID v7、ULID 字符串和 Snowflake long。

本包通过 package manifest 声明默认服务、Options 和 lifecycle，不提供 AddSparkdoIdGeneration() 手工启用入口，也不包含 IdGeneration bootstrap contribution。

默认实现

服务 默认实现 行为
IGuidGenerator / IIdGenerator<Guid> Version7GuidGenerator 调用 Guid.CreateVersion7()。
IStringIdGenerator / IIdGenerator<string> UlidStringIdGenerator 生成 26 位 Crockford Base32 ULID。
ILongIdGenerator / IIdGenerator<long> SnowflakeLongIdGenerator 共享 singleton SnowflakeIdState。
IIdGeneratorProvider DefaultIdGeneratorProvider 提供默认、内置名称和 keyed 扩展解析。

内置名称固定为 guid、ulid 和 snowflake。默认注册使用 TryAdd，应用预注册的服务优先。

Snowflake 生命周期

Snowflake 使用 41-bit timestamp + 10-bit worker id + 12-bit sequence。应用 startup lifecycle 会先通过 IDistributedLock 获取并续租 worker id；只有 startup 成功后才能调用 ILongIdGenerator.Create()。

以下状态均 fail closed：

  • startup 尚未获取 lease；
  • worker lease 已丢失；
  • 物理时钟发生回拨；
  • timestamp 超出 41-bit 范围。

同步生成路径不会等待异步锁，也不会在 lease 丢失后自动重连。

配置

SnowflakeIdGeneratorOptions 提供 Epoch、WorkerLeaseDuration 和 WorkerRenewalInterval。默认 epoch 为 2025-01-01T00:00:00Z，lease duration 为 30 秒，renewal interval 为 10 秒。renewal interval 必须严格短于 lease duration。

应用负责提供符合部署范围的 IDistributedLock。同进程多 Host、跨进程或跨机器生成 Snowflake Id 时，必须使用共享的真实分布式锁 provider。

完整使用说明、边界和验证命令见仓库中的 src/id-generation/README.md。
