io.ray.streaming.runtime.master.resourcemanager.strategy.impl.PipelineFirstStrategy

所有已实现的接口:

ResourceAssignStrategy

public class PipelineFirstStrategy
extends Object
implements ResourceAssignStrategy

Based on Ray dynamic resource function, resource details(by ray gcs get) and execution logic diagram, PipelineFirstStrategy provides a actor scheduling strategies to make the cluster load balanced and controllable scheduling. Assume that we have 2 containers and have a DAG graph composed of a source node with parallelism of 2 and a sink node with parallelism of 2, the structure will be like:

   container_0
             |- source_1
             |- sink_1
   container_1
             |- source_2
             |- sink_2
