Eventual Consistency Strong Consistency 设计中 blocking request 是一个非常常见的情况,当系统承受大规模 update/insert 时,整体 throughput 性能会收到很大影响。那有没有更合适的其它方案呢? Eventual Consistency 来了:它保证当一个 update/insert 发生后,所有的 read request 会最终 (eventual) 读取到操作发生后...
CP systems employ a type of consistency called “strong consistency”. While AP systems guarantee a type of consistency called “eventual consistency” Two types of consistencies: strong consistency v eventual consistency https://levelup.gitconnected.com/eventual-consistency-and-strong-consistency-d0b88...
人们为乐观复制系统提出了各种一致性模型,其中最著名的是eventual consistency 最终一致性。...上图给出了一个稍强的一致性模型称为strong eventual consistency强最终一致性,通常更合适 [Shapiro et al., 2011]。
Consistency refers to a database query returning the same data each time the same request is made. Strong consistency means the latest data is returned, but, due to internal consistency methods, it may result with higher latency or delay. With eventual consistency, results are less consistent ea...
> You frequently need to __trade strong consistency for availability__. This means that you may need to design some aspects of your solutions around the notion of eventual consistency and accept that the data that your applications use might not be completely consistent all of the time. The ...
Eventual Consistency: ensures eventual consistency of cache even in extreme cases Strong consistency: provides strong consistent access to applications Anti-breakdown: a better solution for cache breakdown Anti-penetration Anti-avalanche Batch Query

Furthermore, as availability has the most significant impact on revenue, ultimately the system design of distributed data stores for businesses reduces to a choice between different eventual consistency recovery strategies. Seen in this light, although blockchain is a strong eventual consistency recovery...

In this paper, we introduce strong eventually consistent replicated objects (SECROs), a general-purpose data type for building available data structures that guarantee strong eventual consistency (SEC) without restrictions on the operations. To evaluate our solution we compare a realtime collaborative ...
