  in the documentation of assistant (preview) there is the possibility to delete expired data: 

e.g. : vector_store = client.beta.vector_stores.create_and_poll( name="Product Documentation", file_ids=['file_1', 'file_2', 'file_3', 'file_4', 'file_5'], expires_after={ "anchor": "last_active_at", "days": 7 } )

this is the link:

have you already tried it to implement this into the current code? 

Where to start? 
Thanks and best regards

I have not tried to implement such a feature, no. This is the first time it's been requested.

To implement it, we need a few things:

1. A way of marking the expiration time of a file (if it's not going to be a global expiration). We could potentially store that in the metadata of the blob, I suppose.
2. A way of querying for expired files. Perhaps using https://learn.microsoft.com/en-us/azure/storage/blobs/storage-manage-find-blobs?tabs=azure-portal if we're using Blob metadata. Or we have to do a brute-force search over every blob and decide.
3. A cron job for deleting expired data. Since we're hosted on AppService, that'd be via WebJobs: https://learn.microsoft.com/en-us/azure/storage/blobs/storage-manage-find-blobs?tabs=azure-portal

So I think it is doable, but is a decent amount of work. I likely will not be implementing it anytime soon, as there are other feature requests that are more commonly requested. If you do implement it, we'd love to see it in a branch or PR.
