ExecutionJobVertex (Flink : Runtime 1.15.0 API)

java.lang.Object
- org.apache.flink.runtime.executiongraph.ExecutionJobVertex

所有已实现的接口:

org.apache.flink.api.common.Archiveable<ArchivedExecutionJobVertex>, AccessExecutionJobVertex
```
public class ExecutionJobVertex
extends Object
implements AccessExecutionJobVertex, org.apache.flink.api.common.Archiveable<ArchivedExecutionJobVertex>
```
An ExecutionJobVertex is part of the ExecutionGraph, and the peer to the JobVertex.
The ExecutionJobVertex corresponds to a parallelized operation. It contains an ExecutionVertex for each parallel instance of that operation.

```
    A utility function that computes an "aggregated" state for the vertex.
    This state is not used anywhere in the coordination, but can be used for display in dashboards to as a summary for how the particular parallel operation represented by this ExecutionJobVertex is currently behaving.
    For example, if at least one parallel task is failed, the aggregate state is failed. If not, and at least one parallel task is cancelling (or cancelled), the aggregate state is cancelling (or cancelled). If all tasks are finished, the aggregate state is finished, and so on.
    
    参数:
    
    verticesPerState - The number of vertices in each state (indexed by the ordinal of the ExecutionState values).
    
    parallelism - The parallelism of the ExecutionJobVertex
    
    返回:
    
    The aggregate state of this ExecutionJobVertex.
