> Today, we compare the whole path when deciding if a file is new in the FileSource for structured streaming.  However, this cause cause false negatives in the case where the path has changed in a cosmetic way (i.e. changing s3n to s3a).  We should add an option {{fileNameOnly}} that causes the new file check to be based only on the filename (but still store the whole path in the log).
