> Currently, we write compacted data to a temporary location and then move the files to
a final location, which is an expensive operation on some cloud file systems. Since HIVE-20823
is already in, it can control the visibility of compacted data for the readers. Therefore,
we can perhaps avoid writing data to a temporary location and directly write compacted data
to the intended final path.
