如何有效地使用逻辑应用程序检查foreach中的条件？

我有两个数组变量，每一个我进一步比较abd过程的值，但是问题是，当我有1000条记录时，要花很多时间执行。

Variable_1大约有10条记录 如果HTTP将包含约1000多个记录，则会输出Variable_2 

Variable_1 = 
[
    {

      "Name": "AAA",
      "OwnerId": "121a",

    },
    {

      "Name": "BBB",
      "OwnerId": "123b",

    },
    ...
]

和

Variable_2 = 
[
    {     
      "Demo_Name": "AAA"     
    },
    {  
      "Demo_Name": "BBB"
    },
    {  
      "Demo_Name": "BBB"
    },
    {  
      "Demo_Name": "BBB"
    },
    {  
      "Demo_Name": "BBB"
    }
    .... 
]

我使用了2 for each one is for Variable_1 and another is for Variable_2''。

，然后比较Variable_1.Name == Variable_2.Demo_Name one by one。

因此，当Variable_2的数量超过1000+ records时，大约要花一个小时才能一一检查状况

有什么解决方案可以快速实现吗？ 外循环大约需要2小时 enter image description here

  

如果我尝试concurrent execution，则increment variable设置错误   值

答案 0 :(得分：1)

我尝试使用Azure存储表作为结果的源来执行此操作，只是为了了解我可以快速遍历具有1465条记录的Var2和具有9条记录的Var1的过程。我在这里做了两次，只是想弄清楚最简单的方法。这里的结果是XXXX匹配，存储在Azure存储表中的值，我将在循环完成后获取该值。我添加了一个终止动作，您可以将它们移到动作For each之前，只是为了在每个循环中使用其中之一而不是两者。

作为记录，不确定是否正是您想要的。同样，通过这种方式，如果将For Each数组切换为在Var1而不是Var2上循环，则可以在不到10秒的时间内完成所有对象的操作。如果将其分成不同的数组，则可以过滤两个数组，也可以使用交集。您需要做的就是从JSON表示形式的Azure存储表中获取记录，现在将GUID作为ID。

4分钟 4 Minutes

这是两个循环中第一个循环的流程，我最喜欢的那个循环感觉更干净。 enter image description here

存储表结果，您需要将其截断或完成后执行以下操作： Azure Storage Table

您需要一个Azure存储表来将结果卸载到。 发布时，我减小了Var2的大小，因为发布1600个对象没有意义。 代码：
