要调用动态并行步骤函数,你可以使用AWS Step Functions的内置功能和表达式来动态定义并行步骤。下面是一个用于调用动态并行步骤函数的解决方法,包含了代码示例:
[
{
"FunctionArn": "arn:aws:states:REGION:ACCOUNT:function:FUNCTION_NAME",
"InputPath": "$.input1"
},
{
"FunctionArn": "arn:aws:states:REGION:ACCOUNT:function:FUNCTION_NAME",
"InputPath": "$.input2"
},
...
]
"ParallelState": {
"Type": "Parallel",
"InputPath": "$",
"ResultPath": "$.parallelResult",
"Branches": [
{
"StartAt": "InvokeFunction1",
"States": {
"InvokeFunction1": {
"Type": "Task",
"Resource": "arn:aws:states:REGION:ACCOUNT:function:FUNCTION_NAME",
"InputPath": "$.input1",
"End": true
}
}
},
{
"StartAt": "InvokeFunction2",
"States": {
"InvokeFunction2": {
"Type": "Task",
"Resource": "arn:aws:states:REGION:ACCOUNT:function:FUNCTION_NAME",
"InputPath": "$.input2",
"End": true
}
}
},
...
],
"End": true
}
"StepFunctionInvoke": {
"Type": "Task",
"Resource": "arn:aws:states:REGION:ACCOUNT:function:FUNCTION_NAME",
"InputPath": "$.parallelResult",
"ResultPath": "$.stepFunctionResult",
"Parameters": {
"FunctionArn": "arn:aws:states:REGION:ACCOUNT:function:FUNCTION_NAME",
"Input.$": "$.inputList"
},
"End": true
}
注意:在上述示例中,REGION、ACCOUNT和FUNCTION_NAME需要替换为实际的AWS区域、AWS账号和步骤函数的ARN。
以上就是调用动态并行步骤函数的解决方法,包含了代码示例。你可以根据自己的需求进行修改和定制。
