Hey @ancient-wolf-19325 how to delay task retry in case first execution has failed?
j
To delay a task retry in Flyte, you can use the
Retry
function from the Flyte codebase, which allows you to specify a delay between retry attempts. The
Retry
function takes the number of attempts, a delay duration, and a function to execute. Here's a basic example:
Copy code
import (
	"time"
	"github.com/flyteorg/flyte/flytestdlib/logger"
)

func Retry(attempts int, delay time.Duration, f func() error) error {
	return RetryOnSpecificErrors(attempts, delay, f, retryOnAllErrors)
}
This function will retry the specified function
f
with a delay between attempts. You can adjust the
delay
parameter to set the desired delay duration. Would you like more details on implementing this in a Flyte task? Sources: - Flyte GitHub File 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@ancient-wolf-19325 please write a sample Python code to describe how to use retry function.

Flyte does not natively support specifying a delay between retries directly in the task decorator. However, you can implement a custom retry logic within the task itself using Python's
time.sleep
to introduce a delay. Here's a sample code snippet demonstrating this approach:
Copy code
import time
from flytekit import task
from flytekit.exceptions.user import FlyteRecoverableException

@task(retries=3)
def my_task() -> None:
    try:
        # Simulate task logic that might fail
        raise Exception("Simulated failure")
    except Exception as e:
        # Introduce a delay before retrying
        time.sleep(5)  # Delay for 5 seconds
        raise FlyteRecoverableException("Retrying after delay") from e
This code uses
time.sleep
to delay the retry by 5 seconds after a failure. The
FlyteRecoverableException
is used to indicate that the task should be retried. Would you like more details on this approach? Sources: - Flyte Documentation on Retries 👍 1 button 👎 0 button 💡 Hint: Mention @ancient-wolf-19325 in the thread for followups.
