With the "simplifying" technique of keeping the leaf level in a separate file, it becomes hard to distinguish from Heikki's Grouped Index Tuples approach when you include the "maintain cluster order" patch. That really looks like where anyone should work from for any IOT effort. It appears to have been largely completed years ago. For those who missed or forgot it, this is the latest I could find: http://community.enterprisedb.com/git/ Heikki, any thoughts on what it would take, beside cleaning up bit rot? -Kevin
