> Presently for CTAS with external tables, there are two renames, operations,
> one from tmp to _ext and then from _ext to actual target.
> In case of object stores, the renames lead to actual copy. Avoid renaming by
> avoiding rename from tmp to _ext, but by creating a list of files to be
> copied in that directly, which can be consumed in the move task, to copy
> directly from tmp to actual target.
