Hm, this comment from 88 days ago is showing in my google alert as 2 days old. Google is srsly messed up. https://news.ycombinator.com/item?id=45101592 But as to the question: #LMDB doesn't store counts of child nodes in each parent page. Doing so would certainly allow for setting a cursor directly to an Nth record, and redhat even submitted a ticket requesting this feature but it didn't seem important enough at the time, and seemed like too much storage cost for a rarely used function.
