> File source V1 supports reading output of FileStreamSink as batch. https://github.com/apache/spark/pull/11897
> We should support this in file source V2 as well. When reading with paths, we first check if there is metadata log of FileStreamSink. If yes, we use `MetadataLogFileIndex` for listing files; Otherwise, we use `InMemoryFileIndex`.
