, task-1
, etc, I'd like to use the string that comes from each iteration to name tasks like customer
, product
, etc.Marvin

from prefect import flow, task
# Define the task with a templated name
@task(task_run_name="Processing {item}")
def process_item(item: str):
# Perform some processing with the item
print(f"Processing {item}")
# Define the flow
@flow
def dynamic_naming_flow(items: list):
for item in items:
process_item(item) # Task name will be "Processing {item}"
# Example usage
if __name__ == "__main__":
items_to_process = ["customer", "product", "order"]
dynamic_naming_flow(items_to_process)
In this example:
- The @task
decorator is used to define a task named process_item
.
- The task_run_name
parameter within the decorator allows dynamic naming using string templating {item}
.
- The flow dynamic_naming_flow
iterates over items
and calls process_item
for each item.
This way, tasks are named according to the item being processed (e.g., "Processing customer", "Processing product").
For more details on templating in task names, you can refer to the relevant part in the Prefect documentation.

and task_run_name
parameter within the @task
decorator?Marvin

and task_run_name
.
In Prefect:
1. name
:
- This parameter sets a static name for the task itself. This name is used in logs, the Prefect UI, and when referring to the task in code and configuration.
- Example:
python
@task(name="My Custom Task")
def my_task():
pass
- If you have many instances of this task inside the same flow, they will all share this name.
2. task_run_name
:
- This parameter allows dynamic naming for each instance (or run) of the task when the flow is executed. It is useful for templating parts of the task name based on input parameters or other context-specific information.
- Example:
python
@task(task_run_name="Processing {item}")
def my_task(item: str):
pass
- Each execution of this task will have a different name formatted with the specific item
being processed, e.g., "Processing customer", "Processing product".
In essence, name
is for the task itself (static), while task_run_name
is for the individual executions of the task (dynamic).
