    Description

      https://mariadb.com/kb/en/mariadb/server-system-variables/

      Documentation for optimizer_prune_level is unclear on what the value '1' does:
      "If set to 1, the default, the optimizer will use heuristics to prune less-promising partial plans from the optimizer search space. If set to 1, heuristics are disabled and an exhaustive search is performed."
