I have a large file with an MV set I need to do an exploding sort against (about 2 million records, about 20 MVs per record). I'm not actually after any particular sort order but it's taking hours. I'm wondering if there is any efficiency advantage by telling it to use a primary sort on the ID or just to sort on the MV attribute? My (probably flawed) reasoning is that if the primary sort is on the id then the sort process wouldn't have to build up one big explode - as it would have a primary sort by record, it then only needs to explode each record at a time.
Eg. SSELECT BIGFILE BY @ID BY.EXP MV.ATTRIBUTE Or SSELECT BIGFILE BY.EXP MV.ATTRIBUTE Anyone know the answer to that one?
