Figure 8: Election Time Comparison updated. The etcd election time is only the time to determine a leader. We see that the election time for PRaft is relatively constant, taking around 10ms. The etcd implementation is similar in magnitude for smaller number of servers, but the effect of HTTP communication becomes significant beyond 10 servers. Fortunately, we are using etcd, and since etcd provides both TTL on objects, and a compare and swap operation, implementing an election algorithm is trivial. Unelected instances can watch “/election” (or some other well known key) and if it is empty become elected by writing their ID to it.
