A sync-ordered multicast operation is one whose delivery ordering semantics are the same as those for delivering views in a view-synchronous group communication system. In a thingumajig service, operations upon thingumajigs are causally ordered. The service supports lists of users able to perform operations on each particular thingumajig. Explain why removing a user from a list should be a sync-ordered operation.
What will be an ideal response?
Sync-ordering the remove-user update ensures that all processes handle the same set of operations on a thingumajig before the user is removed. If removal were only causally ordered, there would not be any definite delivery ordering between that operation and any other on the thingumajig. Two processes might receive an operation from that user respectively before and after the user was removed, so that one process would reject the operation and the other would not.
