  • Metastability in Recovery: Cascading Recovery with a Loop

    ·

    My last metastable blog post discussed the interactions between systems and components and how they can lead to metastable failures. Specifically, I looked at interactions between systems/components and how signals can be misinterpreted by different systems due to ambiguity — a timeout may mean a transient fault that can be fixed by retrying, but it

    This post is a quick update/conclusion to the part 1. So, does the network variations make any impact at all? In the earlier simulation I showed some small performance degradation going from 3 to 5 nodes. The reality is that for paxos, network behavior makes very little difference on scalability, and in some cases no difference at
