Class StreamGraphOptimizer

java.lang.Object

org.apache.flink.runtime.scheduler.adaptivebatch.StreamGraphOptimizer

public class StreamGraphOptimizer
extends Object

The StreamGraphOptimizer class is responsible for optimizing a StreamGraph based on runtime information.

Upon initialization, it obtains a StreamGraphContext from the AdaptiveGraphManager and loads the specified optimization strategies. At runtime, it applies these strategies sequentially to the StreamGraph using the provided context and information about finished operators.
