How do I implement exponential backoff in my application?

Exponential backoff is a strategy for handling retries in network requests. It involves increasing the wait time between retries exponentially.

Can you give me a code example?

Sure! Here's a simple example in Python:

import time
import random

def exponential_backoff(retries):
    for i in range(retries):
        wait_time = (2 ** i) + random.uniform(0, 1)
        print(f'Waiting for {wait_time:.2f} seconds...')
        time.sleep(wait_time)
        # Here you would attempt your network request

This function waits longer with each retry.

What if the request keeps failing?

If the request keeps failing, you might want to set a maximum wait time or a maximum number of retries to avoid infinite loops.

Are there any libraries that can help with this?

Yes, libraries like tenacity in Python can help manage retries with exponential backoff easily.
