Examples of org.springframework.batch.core.partition.StepExecutionSplitter.split()

org.springframework.batch.core.partition.StepExecutionSplitter.split()
Partition the provided {@link StepExecution} into a set of parallelexecutable instances with the same parent {@link JobExecution}. The grid size will be treated as a hint for the size of the collection to be returned. It may or may not correspond to the physical size of an execution grid.

On a restart clients of the {@link StepExecutionSplitter} should expectit to reconstitute the state of the last failed execution and only return those executions that need to be restarted. Thus the grid size hint will be ignored on a restart. @param stepExecution the {@link StepExecution} to be partitioned. @param gridSize a hint for the splitter if the size of the grid is known @return a set of {@link StepExecution} instances for remote processing @throws JobExecutionException if the split cannot be made
