Expand description

业务作用:描述一次 Saga 创建请求。

Fields§

§saga_id: &'a SagaId

实例身份,由调用方生成(如 UUID 文本)。

§tenant: &'a TenantId

规范化租户;无租户部署传固定 system tenant。

§workflow: &'a WorkflowName

workflow 名称,必须已在注册表注册。

§version: DefinitionVersion

definition 版本。

§business_key: &'a BusinessKey

业务幂等键。

§deadline_at_ms: Option<i64>

实例级业务 deadline(epoch 毫秒);为空则不设全局期限。

§trigger_kind: TriggerKind

初始 transition 的触发来源。

§trigger_id: &'a str

初始 transition 的触发身份(event id 或管理 operation id)。

§first_command_payload: Option<Value>

首步 execute 命令携带的业务输入;后续步骤由参与方本地事实解析。

§first_command_raw_payload: Option<SagaPayload>

原始首步正文;与兼容 JSON 输入互斥,媒体类型与 schema 纳入请求摘要。

§now_ms: i64

当前时刻(epoch 毫秒),由调用方注入统一时钟。
