ON DELETION ORDER Problem: When a InnoDB index page is under-filled, we will merge it with either the left sibling node or the right sibling node. But this checking is incorrect. When the left sibling node is available, even if merging is not possible with left sibling node, we do not check for the possibility of merging with the right sibling node. Solution: If left sibling node is available, and merging with left sibling node is not possible, then check if merge with right sibling node is possible. rb#2506 approved by jimmy & ima. |
