Review Comment:
Hi, @zhongjiajie , thanks for your comment.
Do you mean reading the byte stream directly from the remote storage instead
of downloading it to the local file system first?
Since there are many types of remote storage, some types may support this
method, and some may not. Maybe it will be a feasible way to download and
process the local files uniformly. WDYT?
