Class DeleteRecord

java.lang.Object

org.apache.hudi.common.model.DeleteRecord

All Implemented Interfaces:

Serializable

public class DeleteRecord
extends Object
implements Serializable

Delete record is a combination of HoodieKey and ordering value. The record is used for HoodieDeleteBlock to support per-record deletions. The deletion block is always appended after the data block, we need to keep the ordering val to combine with the data records when merging, or the data loss may occur if there are intermediate deletions for the inputs (a new INSERT comes after a DELETE in one input batch). NOTE: PLEASE READ CAREFULLY BEFORE CHANGING This class is serialized (using Kryo) as part of HoodieDeleteBlock to make sure this stays backwards-compatible we can't MAKE ANY CHANGES TO THIS CLASS (add, delete, reorder or change types of the fields in this class, make class final, etc) as this would break its compatibility with already persisted blocks.
