Technical Perspective: Getting Consensus for Data Replication

The following paper is a breakthrough in which the authors offer a formula to calculate the probability of reading data that was not written by one of the K most...

Quantifying Eventual Consistency with PBS
From Communications of the ACM

Quantifying Eventual Consistency with PBS

Eventual consistency is often "good enough" for practitioners given its latency and availability benefits. In this work, we explain this phenomenon and demonstrate...
