Priority Queue

Explanation

1. PQueue:

   • p-queue manages a queue of tasks with optional prioritization and concurrency limits.
   • The concurrency option ensures that only a set number of tasks run simultaneously.

2. Priority Handling:

   • The priority is passed via the query string (e.g., ?priority=1&requestId=123).
   • Tasks with a lower priority value are processed first (default priority is 10 if not provided).

3. Middleware Integration:

   • The middleware intercepts requests, adds them to the priority queue, and ensures they are processed in the order defined by the queue.

4. Concurrency Limit:

   • The concurrency: 1 setting ensures that no more than 1 task is processed at the same time.
