Static Methods

classmethod array(item_type)

(experimental) Creates an array of some other type.

Parameters:: item_type (Type) – type contained by the array.
Stability:: experimental
Return type:: Type

classmethod char(length)

(experimental) Fixed length character data, with a specified length between 1 and 255.

Parameters:: length (Union[int, float]) – length between 1 and 255.
Stability:: experimental
Return type:: Type

classmethod custom(input_string, is_primitive=None)

(experimental) Creates a custom type from a raw Glue input string.

Escape hatch for column types the other Schema factories don’t model. The inputString is emitted verbatim and is not validated.

Parameters:

input_string (str) – the Glue input string for the type (for example interval_day_to_second).
is_primitive (Optional[bool]) – whether the type is a primitive (non-nested) data type. Defaults to true.

Stability:

experimental

Return type:

Type

classmethod decimal(precision, scale=None)

(experimental) Creates a decimal type.

Parameters:

precision (Union[int, float]) – the total number of digits, between 1 and 38.
scale (Union[int, float, None]) – the number of digits in the fractional part, between 0 and 38; the default is 0

Return type:

Type

classmethod map(key_type, value_type)

(experimental) Creates a map of some primitive key type to some value type.

Parameters:

key_type (Type) – type of key, must be a primitive.
value_type (Type) – type fo the value indexed by the key.

Stability:

experimental

Return type:

Type

classmethod struct(columns)

(experimental) Creates a nested structure containing individually named and typed columns.

Parameters:: columns (Sequence[Union[Column, Dict[str, Any]]]) – the columns of the structure.
Stability:: experimental
Return type:: Type

classmethod varchar(length)

(experimental) Variable length character data, with a specified length between 1 and 65535.

Parameters:: length (Union[int, float]) – length between 1 and 65535.
Stability:: experimental
Return type:: Type
