Dear team members, I had read the topics and yet seems no one offer an final way to let people estimate how long it will take at the final stage. So i try to read the code and think may be the "cleanGraph" part is the very time-consuming section. So i want to suggest, is that possible to print out the document_name periodically. for example, print out "now is working with the 10000th document: ref10000008.e2-ref20000000e5", and let it show on the screen or file without delay! Many Thanks, best regards,...
