How do I prevent starvation of low-priority tasks when using a retry queue for handling HTTP 429 errors

Question

Can you exaplin how to prevent starvation of low-priority tasks when using a retry queue for handling HTTP 429 errors?

Answer 1

To prevent starvation of low-priority tasks in a retry queue, you can use a priority queue with time-based adjustments to ensure fairness. In Python, the queue.PriorityQueue can manage tasks with priorities.Here is the code snippet you can refer to:

In the above code, we are using the following:

• Priority Levels to assign priorities to tasks (lower value = higher priority).
• Fairness to dynamically adjust priorities for low-priority tasks over time (e.g., increment priority after each retry).
• Thread-Safe, which uses a queue.PriorityQueue for thread-safe operations.

Hence, these approaches ensure that even low-priority tasks are eventually processed.
