Peter Bailis :: Highly Available, Seldom Consistent Data management, distributed systems, and beyond Scalable Atomic Visibility with RAMP Transactions 07 Apr 2014 We recently wrote a paper that will appear at SIGMOD called Scalable Atomic Visibility with RAMP Transactions. This post introduces RAMP Transactions, explains why you should care, and briefly describes how they work. Executive Summary W

Availability is in some sense a much wider concept than uptime, since the availability of a service can also be affected by, say, a network outage or the company owning the service going out of business (which would be a factor which is not really relevant to fault tolerance but would still influence the availability of the system). But without knowing every single specific aspect of the system, t

The TLA+ Proof System (TLAPS) mechanically checks TLA+ proofs. TLA+ is a general-purpose formal specification language that is particularly useful for describing concurrent and distributed systems. The TLA+ proof language is declarative, hierarchical, and scalable to large system specifications. It provides a consistent abstraction over the various “backend” verifiers. The current release of TLAPS

Peter Bailis :: Highly Available, Seldom Consistent Data management, distributed systems, and beyond HAT, not CAP: Introducing Highly Available Transactions 05 Feb 2013 tl;dr: Highly Available Transactions show it’s possible to achieve many of the transactional guarantees of today’s databases without sacrificing high availability and low latency. CAP and ACID Distributed systems designers face har

Tsitsiklis In distributed averaging and consensus algorithms, processors exchange and update certain values (or "estimates", or "opinions") by forming a local average with the values of their neighbors. Under suitable conditions, such a
