What is the consistency issue raised by state transfer?
What will be an ideal response?
When a process joins a group it acquires state S from one or more members of the group. It may then start
receiving messages destined for the group, which it processes. The consistency problem consists of ensuring
that no update message that is already reflected in the value S will be applied to it again; and, conversely, that
any update message that is not reflected in S will be subsequently received and processed.
