It's still under development, this paper proposes it as an enhancement for Cassandra, so benchmarks are a way off. Given its properties it is likely to have similar performance to Tempo and Caesar for consensus (perhaps lower throughput than Tempo but better latency than Caesar). It is not dissimilar to Calvin for multi-shard execution, trading away the NxN sequencing layer (and poor failure properties) for dependency tracking.
Perfect. Will dig through it! I didn't realise leaderless protocols are less robust and the paper sets up the situation quite well.
Thanks, glad to hear it is helpful. Do let me know if you have any feedback, particularly that might help clarify things.
