In order to fully support predicate pushdown via the DataflowPlanOptimizer framework we need two things: 1. Support for optimization in distinct values queries 2. The ability to share components between the DataflowPlanBuilder and the PredicatePushdownOptimizer This update addresses both of these concerns by doing a small restructure of the DataflowPlanBuilder interface for accepting optimizers. Instead of accepting a sequence of optimizer instances, the build_plan method will now accept a sequence of optimization enumerations. Those will then be converted to instances via the factory class added in this change. From there the update to the distinct values plan method signature was a trivial addition. Note - snapshot updates should be limited to ID numbers due to the added call to the DataflowPlanNodeOutputDataSetResolver in the distinct values plan.
