> For situations where a monolithic call to GetFileInfo will be slow, it would be useful to immediately receive any results which *are* ready through an {{AsyncGenerator<std::vector<FileInfo>>}} or so. This is probably a prerequisite of ARROW-8163, where the goal is to begin scanning known fragments while other fragments are still being discovered.
> IIUC, one concrete example would be paging through a long output from S3's ListObjectsV2.
