Isolation levels in ACID are typically used for single instances. However, if you're talking about a distributed system then consistency diagram on Jepsen is more applicable[1]. Raft, for example, can ensure read consistency across a cluster by running reads through the consensus mechanism. LiteFS aims to be the analogue to Postgres/MySQL replication and those generally work great for most applications. [1]: https://jepsen.io/consistency https://jepsen.io/consistency
