Eventual Consistency
A weak consistency model in which replicated copies are expected to converge when no new updates continue to arrive.
Eventual consistency does not guarantee that every read observes the latest completed write. Network delay, replication backlog, or a temporary partition can leave replicas at different versions for a period of time; the core expectation is convergence once new updates stop arriving.
The term does not by itself define conflict resolution. Last-write-wins, version vectors, CRDTs, or application-level reconciliation can produce very different semantics. Data-loss behavior, ordering guarantees, and read-your-writes therefore cannot be inferred from the phrase "eventually consistent" alone.
