Hi Manik, <br>
<br>
in order to provide correct answers to your questions, I want to
ask you the following:<br>
<br>
- Why do you say that the current MVCC implementation is
non-genuine? I think that for any transaction T, only the sites
that replicate the data items read/written by T exchange messages
during the execution of T and in order to decide the final outcome
of T. Is it correct?<br>
</blockquote>
<br>
It's an overloading of the meaning of the word genuine. <br>
<br>
In the paper we referred to the meaning of genuine as of in the
context of partial replication protocols: the algorithm only
involves nodes that maintain data accessed in the tx. <br>
<br>
I think Manik is referring to the fact that ISPN's MVCC
implementation does not guarantee serializability.<br>
<br>
