This is a Swift implementation of the Kossmann and Stocker *Iterative Dynamic Programming* query planning

An Iterative Dynamic Programming Query Planning Library

Description

This is a Swift implementation of the Kossmann and Stocker Iterative Dynamic Programming query planning algorithm. It is generic, and can be used with any system with types conforming to two protocols:

  1. a query plan provider, with methods such as accessPlans and joinPlans
  2. a cost estimator which can produce a Cost type for a plan, and compare two cost values
