如何避免在AWS Step Function中同时执行 [英] How to avoid simultaneous execution in aws step function

问题描述

当前，我有一个用例，即云监视规则将每5分钟触发一次步进功能。如果要在步进功能中运行一个执行，我想有一个逻辑来跳过开始另一个执行。
可以这样做吗？

Currently I have a use case that a cloud watch rule will trigger a step function every 5 minutes. I want to have a logic to skip starting another execution if there is one execution already running in step function. Any way to do that?

推荐答案

您可以使CloudWatch事件规则直接触发Step Function，而不是让它触发Lambda函数。 Lambda函数可以通过 ListExecutions API 。否则，Lambda函数可以通过 StartExecution开始新的执行API 。

Instead of having your CloudWatch event rule trigger the Step Function directly, you could have it trigger a Lambda function. The Lambda function could check if there are any Step Function executions in the RUNNING state, via the ListExecutions API. If not, the Lambda function could start a new execution via the StartExecution API.
