Introduction In this post I’ll introduce RAMP, a family of algorithms for performing atomic reads across partitions when working with distributed databases. The original paper, Scalable Atomic Visibility with RAMP Transactions, was written by Peter Bailis, Alan Fekete, Ali Ghodsi, Joseph M. Hellerstein and Ion Stoica, of UC Berkeley and University of Sydney. Peter has graciously reviewed this blog post to ensure its accuracy. As part of the overview, I’ll explain the RAMP-Fast algorithm, the first of 3 algorithms covered in the paper.
