Query: Seamless Paxos Coordinators   The Paxos algorithm requires a single correct coordinator process to operate.
After a failure, the replacement of the coordinator may lead to a temporary
unavailability of the application implemented atop Paxos. So far, this
unavailability has been addressed by reducing the coordinator replacement rate
through the use of stable coordinator selection algorithms. We have observed
that the cost of recovery of the newly elected coordinator's state is at the
core of this unavailability problem. In this paper we present a new technique
to manage coordinator replacement that allows the recovery to occur
concurrently with new consensus rounds. Experimental results show that our
seamless approach effectively solves the temporary unavailability problem, its
adoption entails uninterrupted execution of the application. Our solution
removes the restriction that the occurrence of coordinator replacements is
something to be avoided, allowing the decoupling of the application execution
from the accuracy of the mechanism used to choose a coordinator. This result
increases the performance of the application even in the presence of failures,
it is of special importance to the autonomous operation of replicated
applications that have to adapt to varying network conditions and partial
failures.
