Paper Review: Consistency Analysis in Bloom: a CALM and Collected Approach
Title and Author of Paper Consistency Analysis in Bloom: a CALM and Collected Approach. Alvaro et al. Summary Distributed programming is difficult for even experienced developers to get correct. Understanding the tradeoff between consistency, availability, and latency, while guaranteeing data correctness, provides a wealth of problems for the application developer. This paper presents a language and method for programmatically verifying distributed consistency. CALM - Consistency and Logical Monotonicity There is a connection between distributed consistency algorithms and logical monotonicity, that is, our programs must be correct even in the face of the delay and re-ordering of messages and data across different nodes in a system. By designing programs with order independence, we can ensure that the logic of the system is maintained within a distributed environment. ...
