Revisiting My Distributed Replication Consistency Models Post

Previously, I made a blog post about common consistency models in distributed state machine replication (SMR). As I am recently picking up my scattered knowledge about distributed replication systems, I found some inaccuracy and ambiguity in that old post. This short post lists some patches and complementary material I revisited on this convoluted topic.

Revisited Material

• Decentralized Thoughts blog series: a really good blog series on consensus problems. Although most of the advanced blog posts there focus on decentralized Byzantine-fault-tolerant systems, the beginner posts offer a great summary of the problem and the foundational models we are studying.
• My half-completed technical report: a “somewhat formal” summary of non-transactional consistency models and availability models for distributed replication. This report corrects some inaccuracy/errors in my previous blog post and extends it to a broader scope.
