> Key: ARROW-10222
> URL: https://issues.apache.org/jira/browse/ARROW-10222
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Affects Versions: 1.0.1
> Reporter: Ben Kietzman
> Assignee: Antoine Pitrou
> Priority: Minor
> Fix For: 8.0.0

> Making the transform FS -> URI bijective would greatly simplify unambiguous
> location of files and serialization of filesystems. Something like:
> {code}
> Result<std::string> FileSystem::MakeUri(std::string path = "/");
> {code}
> Difficulties:
> - SubTreeFileSystem::MakeUri("/") would probably return a URI referring to
> its base directory in the wrapped filesystem, which wouldn't roundtrip to a
> SubTreeFileSystem with FileSystemFromUri
> - Not all of s3's parameters are supported in a URI
