> 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.
