Interface PartitionAnalyzer

Contents
  • All Known Implementing Classes:
    AbstractPartitionAnalyzer

    public interface PartitionAnalyzer
    PartitionAnalyzer receives control to process data and final results from each partition. If a PartitionCollector is configured on the step, the PartitionAnalyzer receives control to process the data and results from the partition collector. While a separate PartitionCollector instance is invoked on each thread processing a step partition, a single PartitionAnalyzer instance runs on a single, consistent thread each time it is invoked.
