Unable to correctly handle file download with multiple deployments

[jamie0725]

Describe the bug

I notice a weird problem while using the download functionality inside gr.File() when I deploy my app in multiple pods.

Consider the following case and two pods:

• I have a function that processes user requests which generates an Excel file at the end, the process is handled by pod A, so the file is stored locally inside pod A.
• Now the user wants to click download, but sometimes this download request is handled by pod B. Therefore, the file download request will fail since the file is never generated in pod B.
• If the user clicks the download button multiple times, he will eventually download the file successfully -- when the download request is handled by pod A.

Although gr.File() can take a URL as input/output, for corporate scenarios, we can't upload the file to somewhere public.

What I can think of in the first place is that, when I finish generating the file, I upload it to a private GCS bucket, and when the user clicks download, I download it from GCS so I can ensure every pod has the file ready.

Alternatively, is there a way to ensure the file download request is handled by the same pod as where the file is generated?

@abidlabs, sorry for bothering again...
