------------------------------------
Summary: [C++] Provide streaming output from GetFileInfo
Key: ARROW-11924
URL: https://issues.apache.org/jira/browse/ARROW-11924
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Affects Versions: 3.0.0
Reporter: Ben Kietzman
Assignee: Antoine Pitrou
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.
