That's still going to have to do a tablescan on the whole dataset (a
couple of terabytes?) before building the index isn't it? that doesn't
sound like something you'd want to do too often.
Are there any thoughts of deferring index update so that many rows
can be merged simultaneously, rather than doing many individual index
operations? It sounds as though this is what Thomas is really after and
it would also remove the need for dropping indexes while doing a bulk
insert of data. I apologise if this has been discussed before!
