> Tajo worker generates a physical plan from a logical plan received from QueryMaster. However, some plans need to force a physical planner to choose specified algorithms. 
> Traditionally, Enforcer plays a role to provide physical properties of a query plan and enforce physical algorithms. We also need this feature.
