This sounds like a case of "premature optimization is the root of all evil." Do you have any performance numbers that show UUIDs being any noticeably slower? A UUID is only the size of two 64-bit integers anyway. And either identifier likely will be a tiny fraction of the data in a particular row. So I'd doubt this is any real performance problem in the vast majority of applications. UUIDs look big and scary in hex notation, but underneath it's a compact and fast binary format, just a 128-bit integer. |
