Azure耐用功能。编排会产生许多不必要的活动

时间：2018-09-21 06:52:35

标签： c# azure orchestration azure-durable-functions

我正在尝试使用持久功能进行一些数据转换。为此，我有一个TimerTriggered函数，该函数调用Orchestration函数，然后产生转换活动。

我的问题是，在Orchestration函数被调用时，它立即产生了很多活动，甚至没有到达启动该函数的代码部分。我的编排功能只能启动3个活动，因为我的dataList仅包含3个元素。

但是可以看到，在下面包含的日志输出中，在调用了编排函数之后，在包含 context.CallActivityAsync 的循环开始之前，许多活动函数将立即运行

我根本找不到任何原因。在启动了许多活动之后，我的循环将实际运行并启动我期望的3个活动。

TimerTriggered函数：

[FunctionName("StartupFunc")]
public static async Task Run([TimerTrigger("0 */5 * * * *", RunOnStartup = true, UseMonitor = false)]TimerInfo myStartTimer, [OrchestrationClient] DurableOrchestrationClient orchestrationClient, TraceWriter log)
{
    log.Info("*** STARTUP FUNCTION *** - Time triggered");
    List<OrchestrationModel> ExportModels = await getData();

    log.Info("** Orchestration Start **");
    string id = await orchestrationClient.StartNewAsync("OrchestratorFunc", ExportModels);
    log.Info("** Orchestration End **");
}

编排功能：

[FunctionName("OrchestratorFunc")]
public static async Task<string> TransformOrchestration([OrchestrationTrigger] DurableOrchestrationContext context, TraceWriter log)
{
    var dataList = context.GetInput<List<OrchestrationModel>>();

    foreach (var data in dataList)
    {
        await context.CallActivityAsync<string>("TransformToFormat", new TransformModel(data));
    }
}

活动功能：

[FunctionName("TransformToFormat")]
[public static async Task<string> RunTransformation([ActivityTrigger] DurableActivityContext context, TraceWriter log)
{
    log.Info($"*** TRANSFORM FUNCTION - ACTIVITY *** executed at: {DateTime.Now}  ({context.InstanceId})");
    TransformModel = context.GetInput<TransformModel>();

    //Do some work with TransformModel
    log.Info($"* 1 ({context.InstanceId})");
    //Do more work
    log.Info($"* 4 ({context.InstanceId})");
    return $"return value ({context.InstanceId})");
}

日志输出：

答案 0 :(得分：2)

首先，请勿将RunOnStartup = true用于计时器触发器。它会在将来的版本中删除，因为它会给人们带来很多问题和混乱。这可能与您遇到的问题有关。

您描述的内容听起来像是您在过去创建了一堆尚未完成的业务流程，而这些活动执行与这些旧的，尚未完成的业务流程相对应。编排是持久且长期运行的，因此即使您关闭功能应用程序并重新启动它，它们也将继续尝试运行直到完成或失败。

如果要从头开始，请更改task hub的名称或删除Azure存储队列中的所有消息。
