------------------------------------
Summary: [C++] Add FileSystem::MakeUri() to serialize file
locations to URIs
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
Fix For: 3.0.0
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
