The document you expected this should be explained

when i use find method with preload and then it generated multiple sql log to the console,but the order of sql log output made me confusion, and i search from google and baidu, not body talk about the order of the sql log output. so it is default behavior?

Expected answer

i think it the console may be output the order of the sql log like below result
