High-Performance Transactional Event Processing

Rachid Guerraoui, Jesper Honig Spring, Antonio Cunei

This paper presents a transactional framework for low-latency, high-performance, concurrent event processing in Java. At the heart of our framework lies Reﬂexes, a restricted programming model for highly responsive systems. A Reﬂex task is an event process ...

Transactions in the Jungle

Rachid Guerraoui, Michal Kapalka, Vasu Singh

Transactional memory (TM) has shown potential to simplify the task of writing concurrent programs. However, the semantics of interactions between transactions managed by a TM and non-transactional operations, while widely studied, lacks a clear formal spec ...

Improving OLTP Scalability Using Speculative Lock Inheritance

Anastasia Ailamaki, Frederick Ryan Johnson, Ippokratis Pandis

Transaction processing workloads provide ample request level concurrency which highly parallel architectures can exploit. However, the resulting heavy utilization of core database services also causes resource contention within the database engine itself a ...

Toward a Theory of Input Acceptance for Transactional Memories

Vincent Gramoli, Pascal Felber

As opposed to database transactional systems, transactional memory (TM) systems are constrained by real-time while treating their input workload. Nevertheless, there is no clear formalization of how a TM should react regarding to a specific input. While TM ...

Transparent scalable database replication

Sameh Mohamed Elnikety

This thesis demonstrates that, despite earlier projections to the contrary, database replication on a cluster of low-cost commodity servers can transparently scale database performance. In a replicated system providing the standard transactional properties ...

Temporal streams in commercial server applications

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman

Commercial server applications remain memory bound on modern multiprocessor systems because of their large data footprints, frequent sharing, complex non-strided access patterns, and long chains of dependant misses. To improve memory system performance des ...

Tashkent: Uniting Durability with Transaction Ordering for High-Performance Scalable Database Replication

Sameh Mohamed Elnikety, Fernando Pedone

In stand-alone databases, the functions of ordering the transaction commits and making the effects of transactions durable are performed in one single action, namely the writing of the commit record to disk. For efficiency many of these writes are grouped ...

Transactional Memory

James Richard Larus

The advent of multicore processors has renewed interest in the idea of incorporating transactions into the programming model used to write parallel programs. This approach, known as transactional memory, offers an alternative, and hopefully better, way to ...

Consistent Main-Memory Database Federations under Deferred Disk Writes

Rodrigo Malta Schmidt, Fernando Pedone

Current cluster architectures provide the ideal environment to run federations of main-memory database systems (FMMDBs). In FMMDBs, data resides in the main memory of the federation servers. FMMDBs significantly improve performance by avoiding I/O during t ...

Looking Ahead in Open Multithreaded Transactions

Maxime Monod

Complex distributed object-oriented systems often need complex concurrency features, which may go beyond the traditional concurrency control associated with separate method calls. A transaction groups together a sequence of operations, and can therefore en ...

Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
