From: Rob Sargent <robjsargent@xxxxxxxxx> > Sorry if I missed it, but have we seen the size range of these json files? Not that I've seen, but that's an implementation detail for whoever is doing the work. As someone else pointed out, pick the value as needed, whether that's 10, 100, 1000, or whatever. But issuing 1000 lines of "\copy file" sort of commands at a time isn't a big deal by itself. OTOH, you have a good point that 1000 could be too much work for the server to handle, especially if the "-1" flag is also used. As always: test, test, test... 😊 Kevin This e-mail transmission, and any documents, files or previous e-mail messages attached to it, may contain confidential information.
