Classes in org.apache.drill.exec.planner.fragment used by org.apache.drill.exec.planner.fragmentClassDescriptionDescribes an operator's endpoint assignment requirements.Generic interface to provide different parallelization strategies for MajorFragments.Implementation of
FragmentParallelizerwhere fragment requires running on a given set of endpoints.Responsible for breaking a plan into its constituent Fragments.Captures parallelization parameters for a given operator/fragments.Interface to implement for passing parameters toFragmentParallelizer.Parallelizes the query plan.The simple parallelizer determines the level of parallelization of a plan based on the cost of the underlying operations.Implementation ofFragmentParallelizerwhere fragment has zero or more endpoints with affinities.Wrapper class that allows us to add additional information to each fragment node for planning purposes. -
