thanks
I was working on multi level marketing node-mysql project.
there are 30 levels of user , with each user having a sponser user
initiall yi was trying path enumeration method . but the path becomes too large and indexing on it 💥
thanks for this it will definitely solve my problem
finding all decendands and parent is fast but i guess insertion of new node will require multiple updation on table
still its better since users dont register frequentyl
