Hi,
just a question: looking at performance, is a simple key in a big file (10 - 50 gigabytes) much better than a key with a link to another file? And if, at about which percentage would you estimate is the latter being worse?
I'm pondering the idea of not to make seldom-used links (just for statistics) and update any changed values in the file just before running the statistics. Is it worth it? Would you recommend to do so?
