Parallel 狀態會導致 AWS Step Functions 執行每個分支,從該分支的 StartAt欄位中名為 的狀態開始,並盡可能同時執行,並等到所有分支終止 (達到結束狀態) 後再處理Parallel狀態的 Next 欄位。 Parallel 狀態範例 { "Comment": "Parallel Example.", "StartAt": "Lookup
浏览 AWS Step Functions 界面 在深入了解我们的用例的核心功能之前，让我们先登录 AWS 账户后通过以下四个步骤来熟悉 Step Function 界面：在顶部的搜索栏中输入“Step Functions”关键字。从结果中选择相应的图标。点击“开始”图标开始创建第一步功能。最后，由于我们要创建自己的状态机，因此请选择“创建自己的”选...
Process data in parallel steps –Using a Parallel state, Step Functions can process input data in parallel steps. For example, a customer might need to convert a video file into several display resolutions, so viewers can watch the video on multiple devices. Your workflow could send the origina...
More efficient workflows with parallel executionsWhen you’re managing the state of various functions yourself, it can be challenging to obtain high performance from the system. Some orchestration pieces might only be able to process one task at a time, which could slow down the entire application...
开始使用 AWS Step Functions 本节的目标是提供开始使用 AWS Step Functions 的步骤,从了解构建块到浏览 AWS Step Functions 界面。 Step Functions 的构建块 Step Functions 基于以下模块:(1) 状态机,和 (2) 任务,让我们通过一个示例来理解这些概念。 State Machines:定义事件顺序、条件逻辑以及任务执行总体流程的...
AWS step function 状态机的工作流程 工作流程如图: 1.调用 Input Lottery Winners 函数,传入 num_of_winners,进入第二步。 2.Random Select Winners 根据 Input Lottery Winners 的输出(body)调用 Random Select Winners,生成两个获奖号码,进入第三步。
加载所有维度表的Parallel进程通过Next属性为后续的 Store Sales 事实表转换/加载SalesFACTInit设置了一个依赖。SalesFACTInit步骤使用SubmitStoreSalesFACTJob触发 AWS Batch 转换操作,AWS Batch 则是由 AWS Lambda 作业JobStatusPol-SubmitJobFunction触发的。GetStoreSalesFACTJobStatus通过 AWS LambdaJobStatusPoll...
When gathering stack templates, we are currently ignoringREVIEW_IN_PROGRESSstacks as no template is available during the time the stack is in that state. However, stacks inREVIEW_IN_PROGRESShave already passed through the asset uploading step, where it either uploads new assets or ensures that th...
Parallel: Adds parallel branches. Map: Adds a for-each loop. Wait: Delays for a specific time. In the center of the page, you can see the state machine you are currently working on. To build the account validator workflow, you need: ...
