@xiaofan-luan I'll take a stab at this later this week or over this weekend if nobody else beats me to it

@fzliu I suggest using opendal as the access layer for storage. It provides a unified interface to access file systems, memory, S3, etc. Although it is written in Rust, it has bindings for various languages especially Python.

The latest version of GPTCache have implemented it, pr: #213. So i will close the issue. @jiaoew1991 But we didn't use the opendal as the access layer for storage. If we need to access more object storage in the future, we will consider using it.
