Hi,

+1 for making 'no_sort' as default sort_scope

1. Regarding removing empty SORT_COLUMNS option, I don't think we change the
current behaviour as already some users might be using it in their script,
so if we remove empty SORT_COLUMNS option then their scripts start failing
after upgrade. It is better to make that as deprecated. In the future major
releases, we can remove all deprecated options.

2. Regarding David's suggestion, we cannot change the sort columns as it
impacts the compaction. But we can change the sort _scope. So I think it is
better we consider only updating the sort_scope through alter command.

Regards,
Ravindra.
