-----------------------------------
Summary: [C++][Dataset] Allow FileSystemDataset's file list to be
lazy
Key: ARROW-8163
URL: https://issues.apache.org/jira/browse/ARROW-8163
Project: Apache Arrow
Issue Type: Improvement
Components: C++, C++ - Dataset
Affects Versions: 0.16.0
Reporter: Ben Kietzman
Assignee: Ben Kietzman
Fix For: 1.0.0
A FileSystemDataset currently requires a full listing of files it contains on
construction, so a scan cannot start until all files in the dataset are
discovered. Instead it would be ideal if a large dataset could be constructed
with a lazy file listing so that scans can start immediately.
