Hi Sean,

you misunderstud my context. I do not talk about result of cloning but about 
implementation of clone process by FB developers. When i talk about copying 
data i talk about transaction data like flags, tip ... not database data like 
records...

Regards,
Karol Bieniaszewski

Given that the clone would have the details of an **active** transaction, it 
would be isolated from any other transactions just as the active transaction 
would be.

Read-committed/snapshot transactions only see data for transactions which were 
committed before the new transaction started, changes from any commit after 
that are not seen.

So, there is no issue.


Sean
