 * These tests are starting to be a hack.  The files writtern by addDeltaFile() are not proper
 * Acid files and the {@link CompactorTest.MockRawReader} performs no merging of delta files and
 * fakes isDelete() as a shortcut.  This makes files created on disk to not be representative of
 * what they should look like in a real system.

 * delete event handling would be duplicating either OrcRawRecordMerger or VectorizedOrcAcidRowBatchReaer.
