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 کاملEventual Wait-Free Synchronization
Eventually linearizable objects are novel shared memory programming constructs introduced as an analogy to eventual consistency in message-passing systems. However, their behaviors in shared memory systems are so mysterious that very little general theoretical properties of them is known. In this paper, we lay the theoretical foundation of the study of eventually linearizable objects. We prove ...
متن کاملEventual properties of matrices
An eventual property of a matrix M ∈ C is a property that holds for all powers M, k ≥ k0, for some positive integer k0. Eventually positive and eventually nonnegative matrices have been studied extensively, and some results are known for eventually r-cyclic matrices. This paper introduces and establishs properties of eventually reducible matrices, establishs properties of the eigenstructure of ...
