So..., I made the unfortunate decision to try and copy/paste 22,000+ address points into the same file geodatabase. It's taking soooooooo long.... So my question is, how much of a chance is there to corrupt a file geodatabase during a copy/paste operation if you kill the ArcMap process midway thru?
It's difficult, though possible, to corrupt a file geodatabase. You should certainly delete the table that was loading when the application was terminated.
22k points doesn't seem like a lot, so there may be other issues at play here (and these issues may increase the probability of corruption).
I have check the same with copy/paste (5400 polylignes) and kill application before the end but the process is in transactional mode when you are on edit mode. I haven't data corruption after premature kill process. I think this the transactional mode. I have same number of entities as intial step
