flytekit.core.cache.Cache

Cache configuration for a task.

    version: typing.Optional[str],
    serialize: bool,
    ignored_inputs: typing.Union[typing.Tuple[str, ...], str],
    salt: str,
    policies: typing.Union[typing.List[flytekit.core.cache.CachePolicy], flytekit.core.cache.CachePolicy, NoneType],

flytekit.core.cache.CachePolicy

Base class for protocol classes.

Protocol classes are defined as::

class Proto(Protocol):
    def meth(self) -> int:
        ...

Such classes are primarily used with static type checkers that recognize structural subtyping (static duck-typing).

For example::

class C:
    def meth(self) -> int:
        return 0

def func(x: Proto) -> int:
    return x.meth()

func(C())  # Passes static type check

See PEP 544 for details. Protocol classes decorated with @typing.runtime_checkable act as simple-minded runtime protocols that check only the presence of given attributes, ignoring their type signatures. Protocol classes can be generic, they are defined as::

class GenProto[T](Protocol):
    def meth(self) -> T:
        ...

protocol CachePolicy()

get_version()

def get_version(
    salt: str,
    params: flytekit.core.cache.VersionParameters,
) -> str

flytekit.core.cache.VersionParameters

Parameters used for version hash generation.

param func: The function to generate a version for. This is an optional parameter and can be any callable that matches the specified parameter and return types. :type func: Optional[Callable[P, FuncOut]]

class VersionParameters(
    func: typing.Callable[~P, ~FuncOut],
    container_image: typing.Union[str, flytekit.image_spec.image_spec.ImageSpec, NoneType],
    pod_template: typing.Optional[flytekit.core.pod_template.PodTemplate],
    pod_template_name: typing.Optional[str],
)
