Crazy Ideas: OpenDAL REST/gRPC API

[Xuanwo]

Although there are ongoing efforts to expose OpenDAL with public APIs such as s3 and webdav, most of them come with additional costs and are not native to OpenDAL. Therefore, I am considering exposing OpenDAL's native REST and gRPC APIs.

Those API should:

• OpenDAL native: no extra cost, mapping to opendal's API directly.
• Easy to use: no sdk needed, users can call an opendal server without effort.
• Easy to maintain: no complex logic, no state, no cluster, one binary

Benefits:

• Serve as service sidecar (good for K8s users)
• Serve as storage proxy (good for golang users)

Anyone working on this yet?

Not yet. Do you have a use case for this?

Possibly. We have a React front-end that currently calls directly into AWS. I am wondering if we can create a server-side OpenDAL API that works across cloud platforms, and have React call into a GraphQL APIs (or rewrite it into a simpler REST front-end).
