Cure: Strong Semantics Meets High Availability and Low Latency
TLDR
This paper presents the protocols for highly available transactions, and an experimental evaluation showing that Cure is able to achieve scalability similar to NoSQL databases, while providing stronger guarantees. Expand

Distributed transactional reads: the strong, the quick, the fresh & the impossible
TLDR
We show that there is a three-way trade-off between read consistency, read delay (latency), and freshness, and that some desirable combinations are impossible. Expand

2W-FD: A Failure Detector Algorithm with QoS
TLDR
We introduce the Two-Windows Failure Detector (2W-FD), an algorithm able to react to sudden changes in network conditions, property that currently existing algorithms do not satisfy. Expand

Serverless Event-Stream Processing over Virtual Actors
TLDR
A serverless event-stream processing service with pay-for-use and SLA’s must be scalable, highly available, and low cost. Expand

An empirical perspective on causal consistency
TLDR
We identify that protocols that provide causal consistency share the well-known DUR (deferred update replication) algorithmic structure and observe that existing implementations of causal consistency fall into a sub-category of DUR that we name A-DUR. Expand

MW-FD, A Failure Detector Algorithm with QoS, and an Analysis Towards Failure Detection as a Service
Distributed systems provide resources to a large number of applications today. They are designed to provide reliable and continuous services despite the failures of some of their components.Expand
