Hello, We are a group of students trying to repeat the experiments described in the paper Updating a Cracked Database [1]. We know how to use the cracking optimizer, but what we can't figure out is how to select one of the described algorithms to be used for updates. We found implementations of all the algorithms in the source code and I have been looking in documentation and the source code for a considerable time without any luck. Can someone please point us in the right direction? Thanks, Stef Sijben References [1] S. Idreos, M.L. Kersten, and S. Manegold. Updating a cracked database.
