1. It checks if the current number of workers (`count`) is within the allowed range (between `min_workers` and `max_workers`). If not, it adjusts the number to fit within this range.

2. If there are more than (`full_scale_jobs_waiting` OR `max_workers` if not defined) jobs , it will increase the number of workers up to `max_workers` if there are less (otherwise if workers already above or equal taret, do nothing), that's a "full scale-out". Note that full-scale out events are not subject to the cooldown period since they are meant to handle sudden spike.

3. The function looks at the last autoscaling event (`last_event`) to see if it's too soon to make another change (this is called a cooldown period, defined by `full_scale_cooldown_seconds` for full scale out events or `cooldown_seconds` for normal events).

5. If there aren't many jobs waiting, it looks at how busy the current workers are using the `occupancy` data:

The function uses occupancy rates over different time periods (`occupancy_rate_15s`, `occupancy_rate_5m`, `occupancy_rate_30m`) to make decisions, ensuring that changes are based on sustained trends rather than momentary spikes. The 3 values MUST be below or above the threshold to trigger a scale in or out.

The goal is to have just enough workers to handle the current workload (represented by `queue_counts`) efficiently, without having too many idle workers or too few to handle the jobs.
