java.lang.Object

com.northconcepts.datapipeline.transform.Transformer

com.northconcepts.datapipeline.transform.SetBatchSequenceNumberField

public class SetBatchSequenceNumberField
extends Transformer

Adds a sequence (auto increment) field that is incremented with the step value when the value(s) in the specified watch fields differs from the previous record. If no watch fields are specified, the entire record is watched for change. See FieldPath for supported field name expressions.
