public interface RecordProcessor<I,O>

A record processor performs business logic on input records and produces output records. The output record may be of a different type than the input record and will be piped out to the next processor if any. If a record processor throws an exception during processing, the record will be reported as an error. If a record processor returns null, the record will be filtered and next processors in the pipeline will be skipped.
