consistency model

causal consistency

ensures all processes observe causally related operations on objects in identical order across the system

eventual consistency

after updates cease, sufficient time and messaging ensure every node reaches identical final values

history

a collection of operations performed by a system including process information and timing details

linearizability

operations appear to execute atomically in a total order consistent with real-time ordering on single objects

monotonic atomic view

strengthens read committed by requiring that once a transaction observes another's effects, it observes all of them

monotonic reads

each process observes a monotonically advancing system view; once a write is observed, it remains visible
