  output_format: "FormatString",
  compressed: false,
  number_of_buckets: 1,
  serde_info: {
    name: "NameString",
    serialization_library: "NameString",
    parameters: {
      "KeyString" => "ParametersMapValue",
    },
  },
  bucket_columns: ["NameString"],
  sort_columns: [
    {
      column: "NameString", # required
      sort_order: 1, # required
    },
  ],
  parameters: {
    "KeyString" => "ParametersMapValue",
  },
  skewed_info: {
    skewed_column_names: ["NameString"],
    skewed_column_values: ["ColumnValuesString"],
    skewed_column_value_location_maps: {
      "ColumnValuesString" => "ColumnValuesString",
    },
