Cloudflare unveils Meerkat leaderless consensus

Leaderless consensus is the holy grail for global edge networks where latency fluctuations make timeout-based algorithms like Raft a liability.

* By moving away from authoritative leaders, Cloudflare eliminates a major single point of failure and bottleneck, resulting in significantly more resilient control planes.

* Using QuePaxa allows concurrent proposals to constructively interfere rather than collide, which could achieve up to 10x throughput improvement over Raft in highly unstable networks.

* However, the fundamental constraints of wide-area network latency still apply, meaning Meerkat's use case will remain restricted to low-frequency, highly consistent control-plane data rather than general-purpose databases.
