仅当年龄检查成功时才会到达此步骤。调用 lambda 函数来检查日托中心是否有空位。如果有空位，则流程进入下一步。如果没有，则以失败状态结束，通知没有空位。确认注册 这是最后一步，只有日托中心有空位时才能完成。调用 Lambda 函数来确认注册并根据孩子的年龄计算费用。此步骤之后，流程以成功状态结束，确认注册。要...
调用Lambda 函数来确认注册并根据孩子的年龄计算费用。 此步骤之后,流程以成功状态结束,确认注册。 要了解有关 Lambda 函数的更多信息,使用 AWS Kinesis 和 Lambda 进行流数据教您如何使用 AWS 上的无服务器技术处理流数据。 创建IAM 角色 下一步是定义IAM 角色,以便步骤函数可以调用我们的 lambda 函数。具体步骤如...

The billed execution time for the workflow using intrinsics is half that of the workflow using a Lambda function (100ms vs. 200ms). These are Express Workflows, so the total workflow cost is calculated as execution cost + duration cost x number of requests. This means the workflow ...
办法当然是有的。...那么我们是不是可以考虑把checked exception转换成为unchecked exception,然后用在lambda表达式中,这样就可以简化我们的代码,给程序员以更好的代码可读性呢?...并不是,因为我们在map中传入的是一个Function而不是一个专门的异常类。所以我们需要对Function进行额外的处理。...首先JDK中的Function...
