    Description

      `JOIN::tmp_table_param` is initialized during JOIN preparation, however it is used only for creation of the temporary table at optimization phase. Investigate whether it is possible to calculate necessary temporary table parameters right before the actual creation thus eliminating the need of maintaining `JOIN::tmp_table_param` throughout the course of query processing.
