  MyGlueTable:
    Type: AWS::Glue::Table
    Properties:
      DatabaseName: !Ref MyGlueDatabase
      CatalogId: !Ref AWS::AccountId
      TableInput:
        Name: my-glue-table
        Parameters: { "classification" : "json" }
        PartitionKeys:
          - {Name: dt, Type: string}

          Columns:
