Dynamo: amazon's highly available key-value store

TLDR
D Dynamo is presented, a highly available key-value storage system that some of Amazon's core services use to provide an "always-on" experience and makes extensive use of object versioning and application-assisted conflict resolution in a manner that provides a novel interface for developers to use.
Abstract
Reliability at massive scale is one of the biggest challenges we face at Amazon.com, one of the largest e-commerce operations in the world; even the slightest outage has significant financial consequences and impacts customer trust. The Amazon.com platform, which provides services for many web sites worldwide, is implemented on top of an infrastructure of tens of thousands of servers and network components located in many datacenters around the world. At this scale, small and large components fail continuously and the way persistent state is managed in the face of these failures drives the reliability and scalability of the software systems.This paper presents the design and implementation of Dynamo, a highly available key-value storage system that some of Amazon's core services use to provide an "always-on" experience. To achieve this level of availability, Dynamo sacrifices consistency under certain failure scenarios. It makes extensive use of object versioning and application-assisted conflict resolution in a manner that provides a novel interface for developers to use.

When Scalability Meets Consistency: Genuine Multiversion Update-Serializable Partial Data Replication

TL;DR: It is shown that GMU achieves linear scalability and that it introduces negligible overheads (less than 10%), with respect to solutions ensuring non-serializable semantics, in a wide range of workloads.

CumulusRDF: Linked Data Management on Nested Key-Value Stores

Andreas Harth
TL;DR: The feasibility of using a distributed nested key- value store as an underlying storage component for a Linked Data server which provides functionality for serving Linked data via HTTP lookups and in addi- tion offers single triple pattern lookups is investigated.

Towards elastic transactional cloud storage with range query support

TL;DR: In this article, the authors propose ecStore, an elastic cloud storage system that supports automated data partitioning and replication, load balancing, efficient range query, and transactional access, where data objects are distributed and replicated in a cluster of commodity computer nodes located in the cloud.

Time, clocks, and the ordering of events in a distributed system

TL;DR: In this paper, the concept of one event happening before another in a distributed system is examined, and a distributed algorithm is given for synchronizing a system of logical clocks which can be used to totally order the events.
