Syncing large volume of videos taking hours

Hi Team, We are facing the same issue with only 5k videos. However, we need to use the module for 200k videos.

We have enabled API subscription with the event set as "video-change"

This type of event goes on and on with using drush bcsa command set on dedicated cron job resource.
> [notice] Processing "Brightcove API Client queue worker": 2 item(s) remaining out of 2.

Overall it takes about 15-20 hours to complete and that too with inconsistent issues.
