…e with separate primary key and sort key (StarRocks#20035) If we create a primary key table with a separate primary key and sort key, BE maybe crash if we do a schema change in the table(add column/drop column) The reason is that we use column id as the sort key index in the tablet, and we only support reordering the sort key in this pr(StarRocks#13642) which assumes the number of columns in the origin tablet and new tablet during schema change is the same. However, if we add/drop a column, the sort key index in the new tablet will be different from the origin tablet and we will execute reorder which may cause BE crash.
