How can I learn more about how DVC stores the files in an object storage?

Hello.

I'm trying to integrate a labelling system with our data registry (which is a single object storage atm), but I also want to use the same registry with dvc too, so that our raw data reside only in one object storage, which is accessible by both tools.

How can I read more about how data is actually stored in a bucket via dvc? Is it unpacked in a flat way and then organized by a relational db?

Thanks.

DVC stores files as content-addressable storage according to each file's hash. It does not use any relational DB.

Is it the same in the remote object storage?

Yes, the structure of the local cache and remote is the same
