Question

当我收到以下错误时，我试图使用serverless.yml创建24个DynamoDB表。我该如何规避这个？

Serverless: Checking Stack update progress…
.................................................................Serverless: Deployment failed!

Serverless Error ---------------------------------------

 An error occurred while provisioning your stack: TestUserTable
 - Subscriber limit exceeded: Only 10 tables can be created,
 updated, or deleted simultaneously.
Your Environment Information -----------------------------
OS: linux
Node Version: 6.6.0
Serverless Version: 1.1.0

这似乎是Cloudformation的一个普遍问题，这是AWS论坛中的一种解决方法：https://forums.aws.amazon.com/thread.jspa?threadID=167996

我尝试添加dependson，但仍然无法解决问题。

我收到以下错误

ServerlessError: Template format error: Unresolved resource dependencies [Dev1ProductTables] in the Resources block of the template

将DependsOn: "DevPolicyTable"放在引号中也没有任何区别

resources:
  Resources:
    DevUserTable: 
      Type: "AWS::DynamoDB::Table"
      DependsOn: DevPolicyTable
      Properties:
        AttributeDefinitions: 
          - AttributeName: "id"
            AttributeType: "S"
        KeySchema: 
          - AttributeName: "id"
            KeyType: "HASH"
        ProvisionedThroughput: 
          ReadCapacityUnits: 1
          WriteCapacityUnits: 1
        TableName: "b1-dev-user"
      DevPolicyTable:

您已经超出了并行创建的表的数量，最简单的解决方法是使用DependsOn。您可以将一个表依赖项设置到另一个表中，以便在创建依赖表之前不会创建该表。

在此示例中，只有在创建表2之后才创建表1，因此不会并行创建它们。

$db = new \Libs\DB;
$core  = new \Libs\Core;
$controller = new \Libs\Controller;

DynamoDB / CF - 超出订户限制：只能同时创建，更新或删除10个表
