Retries

Retries allow you to re-run a task upon failure. They're pretty easy to configure:

Class-based tasks

For class-based tasks, you can adjust the number of times a task should be retried by setting the RETRIES and RETRY_DELAY_SECONDS class attributes:

• RETRIES: the number of times the task should be retried. Default is 0.

• RETRY_DELAY_SECONDS: the number of seconds to wait in between retries. Must be specified alongside RETRIES. Default is 0.

For example:

# tasks/example_task.py

import prism.task

class ExampleTask(prism.task.PrismTask):
    
    RETRIES = 1
    RETRY_DELAY_SECONDS = 60
        
    def run(self, tasks, hooks):
        test_str = "Hello, world!"
        return test_str

Function-based tasks

For function-based tasks, you can adjust the number of times a task should be retried by setting the retries and retry_delay_seconds keyword arguments to the @task decorator:

• retries: the number of times the task should be retried. Default is 0.

• retry_delay_seconds: the number of seconds to wait in between retries. Must be specified alongside retries. Default is 0.

For example:

# tasks/example_task.py

from prism.decorators import task

@task(
    retries=1,
    retry_delay_seconds=60
)
def example_task(tasks, hooks):
    test_str = "Hello, world!"
    return test_str
