Kian & Arthur
Arthur, I've been working on a new scheduling algorithm that could cut idle time by almost half—thought it’d be worth seeing how that would affect our team's workflow.
That sounds promising—if it can shave idle time in half, we’ll all have more time for the real work. Can you walk me through the main idea and how it would fit into our current pipeline?
Sure. The core idea is a priority queue that orders tasks by their estimated execution time and resource needs. When a worker becomes free, it pulls the next task that best fits the worker’s current load, minimizing idle wait. I’d integrate it into the task dispatcher module, replacing the round‑robin picker. We keep the existing queue interface, just swap the selection logic. That way the rest of the pipeline—logging, monitoring, error handling—stays unchanged. It should be a drop‑in update, just add the new class and adjust the config to point to it.
Nice idea—using a priority queue to match tasks to workers should cut wait time nicely. Have you thought about how you’ll test the new dispatcher before rolling it out, especially around edge cases where a job’s estimate is off? Also, a quick run in staging could confirm the drop‑in claim before we push it to production.
I'll write a unit test suite that covers normal scheduling, zero‑time jobs, and jobs that over‑run the estimate. For each test I’ll compare the expected worker assignment to the actual one. For the estimate‑off scenario I’ll create a job with a low estimate that actually takes longer and verify that the dispatcher falls back to a queue of unfinished tasks instead of blocking the worker. In staging I’ll deploy the new dispatcher behind a feature flag, run the full job mix for an hour, and capture the average idle time per worker. If the metric drops by the target amount and no worker stays idle for longer than a minute, I’ll roll it into production.
Sounds solid—covering those edge cases and using a feature flag gives us safety. Just double‑check that the fallback queue doesn’t starve newer jobs when a worker’s stuck on an overrunning task. If everything lines up, it’ll be a clear win for the team. Good luck with the test run!
Will make sure the fallback queue uses a fairness counter so newer jobs are queued after a set number of attempts. That should prevent any single overrunning task from starving the rest. All right, onto the tests.
