Hi,  
how do I convert below code in serverless format ?  
I am trying to create dynomoDB table  
I also noticed that we have “-” in front for http event what does that mean ?

```
"mySecondDDBTable" : {
  "Type" : "AWS::DynamoDB::Table",
  "DependsOn" : "myFirstDDBTable" ,
  "Properties" : {
    "AttributeDefinitions" : [
      {
        "AttributeName" : "ArtistId",
        "AttributeType" : "S"        
      },
      {
        "AttributeName" : "Concert",
        "AttributeType" : "S"        
      },
      {
        "AttributeName" : "TicketSales",
        "AttributeType" : "S"        
      }
    ],
    "KeySchema" : [
      {
        "AttributeName" : "ArtistId",
        "KeyType" : "HASH"
      },
      {
        "AttributeName" : "Concert",
        "KeyType" : "RANGE"
      }
    ],
    "ProvisionedThroughput" : {
      "ReadCapacityUnits" : {"Ref" : "ReadCapacityUnits"},
      "WriteCapacityUnits" : {"Ref" : "WriteCapacityUnits"}
    },
    "GlobalSecondaryIndexes" : [{
      "IndexName" : "myGSI",
      "KeySchema" : [
        {
          "AttributeName" : "TicketSales",
          "KeyType" : "HASH"
        }
      ],                           
      "Projection" : {
        "ProjectionType" : "KEYS_ONLY"
      },    
      "ProvisionedThroughput" : {
        "ReadCapacityUnits" : {"Ref" : "ReadCapacityUnits"},
        "WriteCapacityUnits" : {"Ref" : "WriteCapacityUnits"}
      }
    }]
  }
```

Wouldn’t using Ref work like described here: [http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-dynamodb-table.html](http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-dynamodb-table.html)

Shameless self-promotion here; I wrote [a blog post](http://blog.rowanudell.com/using-dyanmodb-with-serverless/) on adding DDB to my Serverless Service.
