Enclosing class:

OrcRawRecordMerger

public static final class OrcRawRecordMerger.ReaderKey
extends RecordIdentifier

A RecordIdentifier extended with the current write id. This is the key of our merge sort with the originalWriteId, bucket, and rowId ascending and the currentWriteId, statementId descending. This means that if the reader is collapsing events to just the last update, just the first instance of each record is required.
