prefect.utilities.executors.run_task_with_timeout (task, args=(), kwargs=None, logger=None)[source]
Helper function for implementing timeouts on task executions. The exact implementation varies depending on whether this function is being run in the main thread or a non-daemonic subprocess. If this is run from a daemonic subprocess or on Windows, the task is run in a `ThreadPoolExecutor` and only a soft timeout is enforced, meaning a `TaskTimeoutSignal` is raised at the appropriate time but the task continues running in the background. The task is passed instead of a function so we can give better logs and messages. If you need to run generic functions with timeout handlers, `run_with_thread_timeout` or `run_with_multiprocess_timeout` can be called directly Args: `task (Task)`: the task to execute `task.timeout` specifies the number of seconds to allow `task.run` to run for before terminating `args (Sequence)`: arguments to pass to the function `kwargs (Mapping)`: keyword arguments to pass to the function `logger (Logger)`: an optional logger to use. If not passed, a logger for the `prefect.run_task_with_timeout_handler` namespace will be created. Returns: the result of `f(args, kwargs)` Raises*: `TaskTimeoutSignal`: if function execution exceeds the allowed timeout

prefect.utilities.executors.run_task_with_timeout

(task, args=(), kwargs=None, logger=None)[source]

Helper function for implementing timeouts on task executions.

The exact implementation varies depending on whether this function is being run in the main thread or a non-daemonic subprocess. If this is run from a daemonic subprocess or on Windows, the task is run in a ThreadPoolExecutor and only a soft timeout is enforced, meaning a TaskTimeoutSignal is raised at the appropriate time but the task continues running in the background.

The task is passed instead of a function so we can give better logs and messages. If you need to run generic functions with timeout handlers, run_with_thread_timeout or run_with_multiprocess_timeout can be called directly

Args:

task (Task): the task to execute task.timeout specifies the number of seconds to allow task.run to run for before terminating
args (Sequence): arguments to pass to the function
kwargs (Mapping): keyword arguments to pass to the function
logger (Logger): an optional logger to use. If not passed, a logger for the prefect.run_task_with_timeout_handler namespace will be created.

Returns:

the result of f(*args, **kwargs)

Raises:

TaskTimeoutSignal: if function execution exceeds the allowed timeout
