RPCValet: NI-Driven Tail-Aware Balancing of µs-Scale RPCs

Babak Falsafi, Alexandros Daglis, Mark Johnathon Sutherland

Modern online services come with stringent quality requirements in terms of response time tail latency. Because of their decomposition into fine-grained communicating software layers, a single user request fans out into a plethora of short, μs-scale RPCs, ...

R2P2: Making RPCs first-class datacenter citizens

Edouard Bugnion, Evangelos Marios Kogias, Adrien Ghosn, Georgios Prekas, Jonas Fietz

Remote Procedure Calls are widely used to connect datacenter applications with strict tail-latency service level objectives in the scale of µs. Existing solutions utilize streaming or datagram-based transport protocols for RPCs that impose overheads and li ...

Speculative Linearizability

Rachid Guerraoui, Viktor Kuncak, Giuliano Losa

Linearizability is a key design methodology for reasoning about implementations of concurrent abstract data types in both shared memory and message passing systems. It provides the illusion that operations execute sequentially and fault-free, despite the a ...

A Data-oriented Transaction Execution Engine and Supporting Tools

Anastasia Ailamaki, Frederick Ryan Johnson, Ippokratis Pandis, Danica Porobic, Pinar Tözün, Miguel Sérgio De Oliveira Branco

Conventional OLTP systems assign each transaction to a worker thread and that thread accesses data, depending on what the transaction dictates. This thread-to-transaction work assignment policy leads to unpredictable accesses. The unpredictability forces e ...

Distributed Constraint Optimization : Privacy Guarantees and Stochastic Uncertainty

Thomas Léauté

Distributed Constraint Satisfaction (DisCSP) and Distributed Constraint Optimization (DCOP) are formal frameworks that can be used to model a variety of problems in which multiple decision-makers cooperate towards a common goal: from computing an equilibri ...

JReq: Database Queries in Imperative Languages

Willy Zwaenepoel, Emmanuel Cecchet, Christopher Ming-Yee Iu

Instead of writing SQL queries directly, programmers often prefer writing all their code in a general purpose programming language like Java and having their programs be automatically rewritten to use database queries. Traditional tools such as object-rela ...

Semantic validation in spatio-temporal schema integration

Anastasiya Sotnykova

This thesis proposes to address the well-know database integration problem with a new method that combines functionality from database conceptual modeling techniques with functionality from logic-based reasoners. We elaborate on a hybrid - modeling+validat ...
