Check if it is potentally possible to short-cut the JOIN execution due to

It is possible when the join has "ORDER BY ... LIMIT n" clause, and the
sort+limit operation is done right after the join operation (there's no
grouping or DISTINCT in between).
Then we can potentially build a join plan that enumerates rows in the
ORDER BY order and so will be able to terminate as soon as it has produced
#limit rows.
Note that it is not a requirement that sort_by_table has an index that
matches ORDER BY. If it doesn't have one, the optimizer will pass
sort_by_table to filesort. Reading from sort_by_table won't use
short-cutting but the rest of the join will.
