Hmm, you realise Alvaro is working on MinMax indexes in this release?
They are very efficient with regard to index inserts and specially
designed for use on large tables.
Prior work by Heikki on Grouped Item Tuples was a way of reducing the
size of indexes, yet still allowing uniqueness checks. That is
implemented in SQLServer already and is very useful.
Your comment about the lack of development in indexes seems counter to
the literature that I've seen. The main problem is people keep
patenting things, making it fairly difficult for everyone.
