+/**
+ * An interface could be implemented by vectors that have row id mapping.
+ *
+ * <p>For example, Iceberg's DeleteFile has a row id mapping to map row id to position. This
+ * interface is used to set and get the row id mapping. The row id mapping is an array of integers,
+ * where the index is the row id and the value is the position. Here is an example:
+ * [0,1,2,3,4,5,6,7] -- Original status of the row id mapping array Position delete 2, 6
+ * [0,1,3,4,5,7,-,-] -- After applying position deletes [Set Num records to 6]
