Eventual Consistency
In a replicated database, the consistency level defines whether and how the values of the replicas of a logical object may diverge in the presence of updates. Eventual consistency is the weakest consistency level that guarantees convergence. Informally, it requires that all replicas of an object will eventually reach the same, correct, final value, assuming that no new updates are submitted to ...
متن کاملEventual Consistency for CRDTs
We address the problem of validity in eventually consistent (EC) systems: In what sense does an EC data structure satisfy the sequential specification of that data structure? Because EC is a very weak criterion, our definition does not describe every EC system; however it is expressive enough to describe any Convergent or Commutative Replicated Data Type (CRDT).
متن کاملPrinciples of Eventual Consistency
In globally distributed systems, shared state is never perfect. When communication is neither fast nor reliable, we cannot achieve strong consistency, low latency, and availability at the same time. Unfortunately, abandoning strong consistency has wide ramifications. Eventual consistency, though attractive from a performance viewpoint, is challenging to understand and reason about, both for sys...
متن کاملUnderstanding Eventual Consistency
Modern geo-replicated databases underlying large-scale In-ternet services guarantee immediate availability and tolerate networkpartitions at the expense of providing only weak forms of consistency,commonly dubbed eventual consistency. At the moment there is a lotof confusion about the semantics of eventual consistency, as differentsystems implement it with different sets of ...
متن کاملEventual Extensions of Finite Codes
Suppose S and T are shift equivalent mixing shifts of finite type, and / is a conjugacy from a subsystem of S to a subsystem of T. Then for any sufficiently large n, f extends to a conjugacy of Sn and Tn. A consequence of the proof is a fortified version of Wagoner's Stable FOG Theorem. Recall [Wi] that a nonnegative integral matrix A is the adjacency matrix of a directed graph whose arc set is...
