    Description

      Currently JOIN_TAB::records_read is of type ha_rows. This is an integer type, which prevents proper selectivity and rows estimates. This trivial task has been factored out in order to separate the changes in EXPLAIN due to this change compared to changes in EXPLAIN due to added selectivity estimates.
