Stop the workflow immediately and continue as new.

Parameters
arg:AnySingle argument to the continued workflow.
args:Sequence[Any]Multiple arguments to the continued workflow. Cannot be set if arg is.
workflow:Union[None, Callable, str]Specific workflow to continue to. Defaults to the current workflow.
task_queue:Optional[str]Task queue to run the workflow on. Defaults to the current workflow's task queue.
run_timeout:Optional[timedelta]Timeout of a single workflow run. Defaults to the current workflow's run timeout.

def defn(*, sandboxed: bool = True, dynamic: bool = False) -> Callable[[ClassType], ClassType]:
(source)

Decorator for workflow classes.

This must be set on any registered workflow class (it is ignored if on a base class).

Parameters
cls:Optional[ClassType]The class to decorate.
name:Optional[str]Name to use for the workflow. Defaults to class __name__. This cannot be set if dynamic is set.
sandboxed:boolWhether the workflow should run in a sandbox. Default is true.
dynamic:boolIf true, this activity will be dynamic. Dynamic workflows have to accept a single 'Sequence[RawValue]' parameter. This cannot be set to true if name is present.
failure_exception_types:Sequence[Type[BaseException]]The types of exceptions that, if a workflow-thrown exception extends, will cause the workflow/update to fail instead of suspending the workflow via task failure. These are applied in addition to ones set on the worker constructor. If Exception is set, it effectively will fail a workflow/update in all user exception cases. WARNING: This setting is experimental.
def deprecate_patch(id: str): (source)

Mark a patch as deprecated.

This marks a workflow that had patched in a previous version of the code as no longer applicable because all workflows that use the old code path are done and will never be queried again. Therefore the old code path is removed as well.

Parameters
id:strThe identifier originally used with patched.

@overload
def query(*, name: str) -> Callable[[CallableType], CallableType]:
@overload
def query(*, dynamic: Literal[True]) -> Callable[[CallableType], CallableType]:
(source)

Decorator for a workflow query method.

This is set on any non-async method that expects to handle a query. If a function overrides one with this decorator, it too must be decorated.

Query methods can only have positional parameters. Best practice for non-dynamic query methods is to only take a single object/dataclass argument that can accept more fields later if needed. The return value is the resulting query value. Query methods must not mutate any workflow state.

Parameters
fn:Optional[CallableType]The function to decorate.
name:Optional[str]Query name. Defaults to method __name__. Cannot be present when dynamic is present.
dynamic:Optional[bool]If true, this handles all queries not otherwise handled. The parameters of the method should be self, a string name, and a Sequence[RawValue]. An older form of this accepted vararg parameters which will now warn. Cannot be present when name is present.
def random() -> Random: (source)

Decorator for the workflow run method.

This must be set on one and only one async method defined on the same class as @workflow.defn. This can be defined on a base class method but must then be explicitly overridden and defined on the workflow class.

Run methods can only have positional parameters. Best practice is to only take a single object/dataclass argument that can accept more fields later if needed.

Parameters
fn:CallableAsyncTypeThe function to decorate.
Returns
CallableAsyncTypeUndocumented
def set_dynamic_query_handler(handler: Optional[Callable]): (source)

When set, all unhandled past signals for the given name are immediately sent to the handler.

Parameters
name:strName of the signal.
handler:Optional[Callable]Callable to set or None to unset.
def set_update_handler(name: str, handler: Optional[Callable], *, validator: Optional[Callable] = None): (source)

This overrides any existing handlers for the given name, including handlers created via the @workflow.update decorator.

Parameters
name:strName of the update.
handler:Optional[Callable]Callable to set or None to unset.
validator:Optional[Callable]Callable to set or None to unset as the update validator.

Decorator for a workflow signal method.

This is set on any async or non-async method that you wish to be called upon receiving a signal. If a function overrides one with this decorator, it too must be decorated.

Signal methods can only have positional parameters. Best practice for non-dynamic signal methods is to only take a single object/dataclass argument that can accept more fields later if needed. Return values from signal methods are ignored.

Parameters
fn:Optional[CallableSyncOrAsyncReturnNoneType]The function to decorate.
name:Optional[str]Signal name. Defaults to method __name__. Cannot be present when dynamic is present.
dynamic:Optional[bool]If true, this handles all signals not otherwise handled. The parameters of the method must be self, a string name, and a *args positional varargs. Cannot be present when name is present.

This is the workflow equivalent of time.time_ns.

Returns
intNanoseconds since the epoch

Decorator for a workflow update handler method.

This is set on any async or non-async method that you wish to be called upon receiving an update. If a function overrides one with this decorator, it too must be decorated.

You may also optionally define a validator method that will be called before this handler you have applied this decorator to. You can specify the validator with @update_handler_function_name.validator.

Update methods can only have positional parameters. Best practice for non-dynamic update methods is to only take a single object/dataclass argument that can accept more fields later if needed. The handler may return a serializable value which will be sent back to the caller of the update.

Warning

This API is experimental

Parameters
fn:Optional[CallableSyncOrAsyncType]The function to decorate.
name:Optional[str]Update name. Defaults to method __name__. Cannot be present when dynamic is present.
dynamic:Optional[bool]If true, this handles all updates not otherwise handled. The parameters of the method must be self, a string name, and a *args positional varargs. Cannot be present when name is present.

Upsert search attributes for this workflow.

Parameters
attributes:Union[temporalio.common.SearchAttributes, Sequence[temporalio.common.SearchAttributeUpdate]]The attributes to set. This should be a sequence of updates (i.e. values created via value_set and value_unset calls on search attribute keys). The dictionary form of attributes is DEPRECATED and if used, result in invalid key types on the typed_search_attributes property in the info.
def uuid4() -> uuid.UUID: (source)

Get a new, determinism-safe v4 UUID based on random.

Note, this UUID is not cryptographically safe and should not be used for security purposes.

Returns
uuid.UUIDA deterministically-seeded v4 UUID.
async def wait_condition(fn: Callable[[], bool], *, timeout: Optional[Union[timedelta, float]] = None): (source)

Wait on a callback to become true.

This function returns when the callback returns true (invoked each loop iteration) or the timeout has been reached.

Parameters
fn:Callable[[], bool]Non-async callback that accepts no parameters and returns a boolean.
timeout:Optional[Union[timedelta, float]]Optional number of seconds to wait until throwing asyncio.TimeoutError.

Logger that will have contextual workflow details embedded.

Logs are skipped during replay by default.
