VARIABLE_COMMENT For queries with JOIN and ORDER BY LIMIT : make the optimizer consider a join order that allows to short-cut execution after producing #LIMIT matches if that promises N times speedup. (A conservative setting here would be is a high value, like 100 so the short-cutting plan is used if it promises a speedup of 100x or more). Short-cutting plans are inherently risky so the default is 0 which means do not consider this optimization
