ArrayType

The data type for collections of multiple values. Internally these are represented as columns that contain a scala.collection.Seq.

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

An ArrayType object comprises two fields, elementType: DataType and containsNull: Boolean. The field of elementType is used to specify the type of array elements. The field of containsNull is used to specify if the array has null values.

elementType: The data type of values.
containsNull: Indicates if values have null values

def defaultSize: Int

The default size of a value of the ArrayType is the default size of the element type.
The default size of a value of the ArrayType is the default size of the element type. We assume that there is only 1 element on average in an array. See SPARK-18853.
