case class MapType(keyType: DataType, valueType: DataType, valueContainsNull: Boolean) extends DataType with Product with Serializable

The data type for Maps. Keys in a map are not allowed to have null values.

Please use DataTypes.createMapType() to create a specific instance.

keyType

The data type of map keys.

valueType

The data type of map values.

valueContainsNull

Indicates if map values have null values.
