> If a flags modification leads to no change to current state, we are currently performing
a request to Cassandra to update it to itself.
> This is inefficient and can be avoided.
> Lightweight conditions are expensive so we should care.
> We should thus skip the flag update for this flag. If in a retry loop, the retry loop
should be canceled.
