Interface Summary Interface Description Partitioner Central strategy interface for creating input parameters for a partitioned step in the form ofExecutionContextinstances.PartitionNameProvider Optional interface forPartitionerimplementations that need to use a custom naming scheme for partitions.StepExecutionAggregator Strategy for a aggregating step executions, usually when they are the result of partitioned or remote execution.Class Summary Class Description AbstractPartitionHandler BasePartitionHandlerimplementation providing common base features.DefaultStepExecutionAggregator Convenience class for aggregating a set ofStepExecutioninstances into a single result.MultiResourcePartitioner Implementation ofPartitionerthat locates multiple resources and associates their file names with execution context keys.PartitionStep Implementation ofStepwhich partitions the execution and spreads the load using aPartitionHandler.RemoteStepExecutionAggregator Convenience class for aggregating a set ofStepExecutioninstances when the input comes from remote steps, so the data need to be refreshed from the repository.SimplePartitioner Simplest possible implementation ofPartitioner.SimpleStepExecutionSplitter Generic implementation ofStepExecutionSplitterthat delegates to aPartitionerto generateExecutionContextinstances.TaskExecutorPartitionHandler APartitionHandlerthat uses aTaskExecutorto execute the partitionedSteplocally in multiple threads.
