stack commented on HBASE-8849:
------------------------------
How each codec serializes is up to the code i'd say Ram. If present, codec
could serialize the mvcc or not (probably should). Ditto on deserialize. If
you want to change the cell codec to include mvcc, go ahead; cellcodec was just
a hackup for testing purposes.
> CellCodec should write and read the memstoreTS/mvccVersion

> Cell interface and the corresponding CellCodec provides a new way of
> serializing the Keyvalues.
> Cell interface supports getMvccVersion() and the javadoc says it could be > 0
> if it exists or 0 otherwise.
> But we don't tend to write/read the memstoreTS/mvccVersion in the Cell codec.
