File upload process end up with file being uploaded to some kind of a cloud storage. Once upload is done, there is an automated queuing process that queues the file for processing. This queued state takes some time until file gets processed.
Once processing starts, there will be a record in db with the status.
Question is, how to handle indicator on SPA side before record hits the db?
Client SPA application should somehow indicate that there is a file to be processed but since there is no record in db yet, it has no source it can read the actual status from.
Only thing I can think of is saving it in local storage with some client generated guid and compare by that guid once it hits db.
But, I don't like it since its:
- Doesn't work cross devices
- Involves assumptions for how long can/should something be in that state before discarded from local storage (if background process never picks up and writes to db)
