Has anyone used or seen use of Nested Intervals (see http://www.sigmod.org/sigmod/record/issues/0506/p47-article-tropashko.pdf) in Ruby on Rails? I need something like Nested Sets but also need something that can handle very frequent repositioning, adding and deleting. The problem with Nested Sets is they''re way to heavy for updates. Just curious of any success stories or insight I can get on this. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
