Hailstorm: Disaggregated Compute and Storage for Distributed LSM-based Databases
Willy Zwaenepoel, Laurent Bindschaedler, Ashvin Goel
Distributed LSM-based databases face throughput and latency issues due to load imbalance across instances and interference from background tasks such as flushing, compaction, and data migration. Hailstorm addresses these problems by deploying the database ...
ACM2020AIDE: Accelerating image‐based ecological surveys with interactive machine learning
Devis Tuia, Benjamin Alexander Kellenberger
Ecological surveys increasingly rely on large‐scale image datasets, typically terabytes of imagery for a single survey. The ability to collect this volume of data allows surveys of unprecedented scale, at the cost of expansive volumes of photo‐interpretati ...
2020Online parallel coordinates tool for optimal utility design in the dairy industry
François Maréchal, Ivan Daniel Kantor, Maziar Kermani, Anna Sophia Wallerand
Despite commonly reported potentials for emission reduction and efficiency increase, industrial heat pumps have yet to reach wide-scale employment in non-refrigeration appli- cations. The bottlenecks are identified as a general scepticism from process oper ...
2018Interferometric synthetic aperture microscopy for extended focus optical coherence microscopy
Theo Lasser, Paul James Marchand, Arno Pino Bouwens, Jérôme Extermann, Séverine Coquoz
Optical coherence microscopy (OCM) is an interferometric technique providing 3D images of biological samples with micrometric resolution and penetration depth of several hundreds of micrometers. OCM differs from optical coherence tomography (OCT) in that i ...
2017ReCache: Reactive Caching for Fast Analytics over Heterogeneous Data
Anastasia Ailamaki, Manolis Karpathiotakis, Tahir Azim
As data continues to be generated at exponentially growing rates in heterogeneous formats, fast analytics to extract meaningful information is becoming increasingly important. Systems widely use in-memory caching as one of their primary techniques to speed ...
2017Building Efficient Query Engines using High-Level Languages
We are currently witnessing a shift towards the use of high-level programming languages for systems development. These approaches collide with the traditional wisdom which calls for using low-level languages for building efficient software systems. This sh ...
EPFL2017Building Efficient Query Engines in a High-Level Language
Christoph Koch, Ioannis Klonatos, Amir Shaikhha
Abstraction without regret refers to the vision of using high-level programming languages for systems development without experiencing a negative impact on performance. A database system designed according to this vision offers both increased productivity ...
2016Adaptive Query Processing on Raw Data Files
Nowadays, business and scientific applications accumulate data at an increasing pace. This growth of information has already started to outgrow the capabilities of database management systems (DBMS). In a typical DBMS usage scenario, the user should define ...
EPFL2015NoDB: Efficient Query Execution on Raw Data Files
Anastasia Ailamaki, Miguel Sérgio De Oliveira Branco, Ioannis Alagiannis, Renata Borovica-Gajic
As data collections become larger and larger, users are faced with increasing bottlenecks in their data analysis. More data means more time to prepare and to load the data into the database before executing the desired queries. Many applications already av ...
Assoc Computing Machinery2015H2O: A Hands-free Adaptive Store
Anastasia Ailamaki, Ioannis Alagiannis
Modern state-of-the-art database systems are designed around a single data storage layout. This is a fixed decision that drives the whole architectural design of a database system, i.e., row-stores, column-stores. However, none of those choices is a univer ...
