StreamGraphOptimizationStrategy (Flink : Runtime 2.1.1 API)

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface StreamGraphOptimizationStrategy
```
Defines an optimization strategy for StreamGraph. Implementors of this interface provide methods to modify and optimize a StreamGraph based on contexts provided at runtime.

```
- Method Detail
  - initialize
```
default void initialize(StreamGraphContext context)
```
    Initializes the StreamGraphOptimizationStrategy with the provided StreamGraphContext.
    
    Parameters:
    
    context - the StreamGraphContext with a read-only view of a StreamGraph, providing methods to modify StreamEdges and StreamNodes within the StreamGraph.
  - onOperatorsFinished
```
boolean onOperatorsFinished(OperatorsFinished operatorsFinished,
                            StreamGraphContext context)
                     throws Exception
```
    Tries to optimize the StreamGraph using the provided OperatorsFinished and StreamGraphContext. The method returns a boolean indicating whether the StreamGraph was successfully optimized.
    
    Parameters:
    
    operatorsFinished - the OperatorsFinished object containing information about completed operators and their produced data size and distribution information.
    
    context - the StreamGraphContext with a read-only view of a StreamGraph, providing methods to modify StreamEdges and StreamNodes within the StreamGraph.
    
    Returns:
    
    true if the StreamGraph was successfully optimized; false otherwise.
    
    Throws:
    
    Exception
