After fix for bug 39653 the shortest available secondary index was used for full table scan. Primary clustered key was used only if no secondary index can be used. However, when chosen secondary index includes all fields of the table being scanned it's better to use primary index since the amount of data to scan is the same but the primary index is clustered. Now the find_shortest_key function takes this into account. |
