Enclosing class:

VectorizedOrcAcidRowBatchReader

protected static interface VectorizedOrcAcidRowBatchReader.DeleteEventRegistry

An interface that can determine which rows have been deleted from a given vectorized row batch. Implementations of this interface will read the delete delta files and will create their own internal data structures to maintain record ids of the records that got deleted.
