并行状态在Step Function中合并输出 [英] Parallel States Merge the output in Step Function

问题描述

是否可能具有以下类型的阶跃函数图，即从2个并行状态输出，一个组合状态:

Is it possible to have following kind of Step Function graph, i.e. from 2 parallel state output, one combined state:

如果是，此json的外观如何?如果没有，为什么?

If yes, what would json for this looks like? If not, why?

推荐答案

有可能与下面的相对图

并行状态应如下所示

"MyParallelState": {
  "Type": "Parallel",
  "InputPath": "$",
  "OutputPath": "$",
  "ResultPath": "$.ParallelResultPath",
  "Next": "SetCartCompleteStatusState",
  "Branches": [
    {
      "StartAt": "UpdateMonthlyUsageState",
      "States": {
        "UpdateMonthlyUsageState": {
          "Type": "Task",
          "InputPath": "$",
          "OutputPath": "$",
          "ResultPath": "$.UpdateMonthlyUsageResultPath",
          "Resource": "LambdaARN",
          "End": true
        }
      }
    },
    {
      "StartAt": "QueueTaxInvoiceState",
      "States": {
        "QueueTaxInvoiceState": {
          "Type": "Task",
          "InputPath": "$",
          "OutputPath": "$",
          "ResultPath": "$.QueueTaxInvoiceResultPath",
          "Resource": "LambdaARN",
          "End": true
        }
      }
    }

MyParallelState 的输出将以数组形式从 Parallel状态中的每个状态填充.它们填充在 ParallelResultPath 对象中，并将传递到Next状态

The output of MyParallelState will be populated as in array, from each state in the Parallel state. They are populated within ParallelResultPath object and will be passed into the Next state

{
  "ParallelResultPath": [
    {
      "UpdateMonthlyUsageResultPath": Some Output
    },
    {
      "QueueTaxInvoiceResultPath": Some Output
    }
  ]
}
