> Currently, there is an alter table command that can change the bucketing / sort columns,
as well as the number of buckets (ALTER TABLE table_name CLUSTERED BY (col_name, col_name,
...) [SORTED BY (col_name, ...)] INTO num_buckets BUCKETS). However, this command does not
provide a means to disable bucketing. This proposes to introduce a syntax like
> ALTER TABLE src NOT CLUSTERED;
> that would turn off bucketing.
