Describe the feature you'd like

I hope to implement a batch parsing queue with a maximum concurrency of 10. Any tasks exceeding this limit should enter a waiting queue for sequential processing. This is necessary because some APIs restrict concurrent requests, and parsing takes time (e.g., when running overnight). A queuing mechanism is therefore essential.

Describe implementation you've considered

Additional information

No response

No files, tests, or entry points are named. Start by locating how parsing tasks are submitted and how concurrent parsing is handled, then determine where a maximum concurrency of 10 and a waiting queue belong. Done should mean excess tasks wait and are processed sequentially without exceeding the concurrency limit.
