public class SeqNoFieldMapper extends MetadataFieldMapper
Mapper for the
_seq_no field.
We expect to use the seq# for sorting, during collision checking and for
doing range searches. Therefore the _seq_no field is stored both
as a numeric doc value and as numeric indexed field.
This mapper also manages the primary term field, which has no ES named
equivalent. The primary term is only used during collision after receiving
identical seq# values for two document copies. The primary term is stored as
a doc value field without being indexed, since it is only intended for use
as a key-value lookup.-
