Defined in:

Overview

Background worker to pre-generate the Google Local Inventory feed
and store it in S3 via the Upload model. This ensures the API endpoint
can serve the feed quickly by redirecting to a presigned S3 URL.

Schedule this to run periodically (every 6 hours) to keep the feed fresh.
Can also be triggered manually: GoogleLocalInventoryFeedWorker.perform_async
