… limit involved (apache#39927) For queries like `select * from tbl limit 100;`, we should limit the parallelism to 1. We already have strategies in our code, but we can not control its behavior. So add session variables to control them. Previous pr like apache#33888apache#36535 already has done something similar, this pr integrates them.
