> Currently we do optimization for join queries inside QueryCompiler, which
> makes the APIs and code logic confusing, so we need to move join optimization
> logic into QueryOptimizer.
> Similarly, but probably with a different approach, we need to optimize UNION
> ALL queries and derived table sub-queries in QueryOptimizer.optimize().
