Introducing Meerkat: an experiment in global consensus

Cloudflare Research introduces Meerkat, an experimental internal consensus service that implements the QuePaxa protocol to provide strongly consistent, highly available control-plane state across global data centers; the post explains Meerkat's architecture, how its log ensures linearizability, why QuePaxa offers higher availability than leader-based Raft in wide-area networks, performance trade-offs and limitations, and notes that Meerkat is currently in development with proofs-of-concept but not production deployment.
