- Method Detail
  - getParallelism
```
int getParallelism()
```
    Get the parallelism of current task.
    
    Returns:
    
    the parallelism of this process function.
  - getMaxParallelism
```
int getMaxParallelism()
```
    Get the max parallelism of current task.
    
    Returns:
    
    The max parallelism.
  - getTaskName
```
String getTaskName()
```
    Get the name of current task.
    
    Returns:
    
    The name of current task.
  - getIndexOfThisSubtask
```
int getIndexOfThisSubtask()
```
    Gets the number of this parallel subtask. The numbering starts from 0 and goes up to parallelism-1 (parallelism as returned by getParallelism()).
    
    Returns:
    
    The index of the parallel subtask.
  - getAttemptNumber
```
int getAttemptNumber()
```
    Gets the attempt number of this parallel subtask. First attempt is numbered 0. The attempt number corresponds to the number of times this task has been restarted(after failure/cancellation) since the job was initially started.
    
    Returns:
    
    The attempt number of the subtask.
