    Description copied from interface: StepExecutionSplitter
    The name of the step configuration that will be executed remotely. Remote workers are going to execute a the same step for each execution context in the partition.
    Specified by:
    getStepName in interface StepExecutionSplitter
    Overrides:
    getStepName in class SimpleStepExecutionSplitter
    Returns:
    the name of the step that will execute the business logic

public java.util.Set<StepExecution> split(StepExecution stepExecution,
                                          int gridSize)
                                   throws JobExecutionException
```
    Returns the same number of StepExecutions as the gridSize specifies. Each of the child StepExecutions will not be available via the JsrJobOperator per JSR-352.
    Specified by:
    split in interface StepExecutionSplitter
    Overrides:
    split in class SimpleStepExecutionSplitter
    Parameters:
    stepExecution - the StepExecution to be partitioned.
    gridSize - a hint for the splitter if the size of the grid is known
    Returns:
    a set of StepExecution instances for remote processing
    Throws:
    JobExecutionException - if the split cannot be made
