OLTP in Wonderland -- Where do cache misses come from in major OLTP components?

For several decades, online transaction processing has been one of the main applications that drives innovations in the data management ecosystem, and in turn the database and computer architecture communities. Despite the novel approaches from industry an ...

Enabling efficient OS paging for main-memory OLTP databases

Anastasia Ailamaki, Radu Ioan Stoica

Even though main memory is becoming large enough to fit most OLTP databases, it may not always be the best option. OLTP workloads typically exhibit skewed access patterns where some records are hot (frequently accessed) but many records are cold (infrequen ...

An Open Source Framework for Standardized Comparisons of Face Recognition Algorithms

Sébastien Marcel

In this paper we introduce the facereclib, the first software library that allows to compare a variety of face recognition algorithms on most of the known facial image databases and that permits rapid prototyping of novel ideas and testing of meta-paramete ...

SLICC: Self-Assembly of Instruction Cache Collectives for OLTP Workloads

Anastasia Ailamaki, Pinar Tözün

Online transaction processing (OLTP) is at the core of many data center applications. OLTP workloads are known to have large instruction footprints that foil existing L1 instruction caches resulting in poor overall performance. Prefetching can reduce the i ...

Experimental study on condensation heat transfer in vertical minichannels for new refrigerant R1234ze(E) versus R134a and R236fa

John Richard Thome, Lorenzo Consolini, Farzad Vakili Farahani, Jung Eung Park

Experimental condensation heat transfer data for the new refrigerant R1234ze(E), trans-1,3,3,3-tetrafluoropropene, are presented and compared with refrigerants R134a and R236fa for a vertically aligned, aluminum multi-port tube. Local condensation heat tra ...

On Probabilistic Fixpoint and Markov Chain Query Languages.

Christoph Koch

We study highly expressive query languages such as datalog, fixpoint, and while-languages on probabilistic databases. We generalize these languages such that computation steps (e.g. datalog rules) can fire probabilistically. We define two possible semantic ...

An Automated, yet Interactive and Portable DB designer

Anastasia Ailamaki, Ioannis Alagiannis, Debabrata Dash

Tuning tools attempt to configure a database to achieve optimal performance for a given workload. Selecting an optimal set of physical structures is computationally hard since it involves searching a vast space of possible configurations. Commercial DBMSs ...

PARINDA: An Interactive Physical Designer for PostgreSQL

Anastasia Ailamaki, Thomas Heinis, Ioannis Alagiannis, Debabrata Dash, Cristina Ileana Maier

One of the most challenging tasks for the database administrator is to physically design the database to attain optimal performance for a given workload. Physical design is hard because it requires the selection of an optimal set of design features from a ...

Caching All Plans with Just One Optimizer Call

Anastasia Ailamaki, Ioannis Alagiannis, Debabrata Dash, Cristina Ileana Maier

Modern database management systems (DBMS) answer a multitude of complex queries on increasingly larger datasets. Given the complexities of the queries and the numerous design features, manual design is no longer an option. Instead, automatically designing ...

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.
