我需要做的任务是让CDN依赖于S3存储桶.但我们希望使用现有的存储桶而不是创建新的存储桶.

这是我正在尝试的示例代码:

"Parameters" : {
  "UseExistingBucket" : {
    "Description" : "Yes/No",
    "Default" : "yes",
    "Type" : "String",
    "AllowedValues" : [ "yes", "no" ]
  }
},
"Conditions" : {
  "CreateS3Resources" : {"Fn::Equals" : [{"Ref" : "UseExistingBucket"}, "no"]}
},
"Resources" : {
  "StaticBucket" : {
    "Type" : "AWS::S3::Bucket",
    "Condition" : "CreateS3Resources",
    "Properties" : {
      "BucketName" : { "Fn::Join": [ "-", [ "app",  { "Ref": "EnvType" }, "static" ] ] }
    },
    "DeletionPolicy": "Retain"
  },
  "MyStaticDistribution": {
    "Type": "AWS::CloudFront::Distribution",
    "Properties": {
      "DistributionConfig": { …

Mysql版本<5.6显示变量'sort_buffer_size'和'myisam_sort_buffer_size'.但是当升级到mysql 5.6时,它现在除了前面的两个之外还显示'innodb_sort_buffer_size'.

那么sort_buffer_size与innodb_sort_buffer_size之间的区别是什么？它是替换或新的不同变量.

如果这是重复的问题,请指出我满意的解决方案.
