nonreplicated
Nonreplicated refers to data, state, or services that are stored or operated on a single node without automatic duplication across multiple nodes. In a nonreplicated design, there is no built-in replication factor and no multi-node consensus required to maintain the primary copy. This contrasts with replicated systems that maintain multiple copies to improve fault tolerance and availability.
Nonreplicated components can offer lower write latency and simpler consistency since there is only one copy
Common contexts include single-node databases such as SQLite used as a local store, ephemeral in-memory caches,
To mitigate risk, operators employ external backups, regular snapshots, and disaster-recovery plans. In distributed architectures that
