File format for key-value pairs

When you create a UTF-8 encoded file, use the following JSON format:

{
  "data":[
    {
      "key":"key1",
      "value":"value"
    },
    {
      "key":"key2",
      "value":"value"
    }
  ]
}

Your file can't include duplicate keys. If you specified an invalid file in your Amazon S3 bucket, you can update the file to remove any duplicates and then try creating your key value store again.
