The authors consider the problem of separating consistency-related safety properties from availability and durability in distributed data stores via the application of a \"Bolt-on\" shim layer that upgrades the safety of an underlying general-purpose data store. This shim provides the same consistency guarantees atop a wide range of widely deployed but often inflexible stores. As causal consistency is one of the strongest consistency models that remain available during system partitions, they develop a shim layer that upgrades eventually consistent stores to provide convergent causal consistency.
