Leaderless Consensus: The State of the Art
Roberto Palmieri · 2016
With the reduced cost of hardware due to technological advancements and efficient elastic networks, distributed systems size is increasing to meet better availability requirements. Existing consensus-based transactional systems show limited scalability due to either their reliance on a single leader or increased complexity in ordering mechanism. In this position paper we outline state-of-the-art solutions, highlight their weaknesses, and propose a vision to enhance leaderless consensus protocols by using reliable fast deliveries.
