Using Read Promotion and Mixed Isolation Levels for Performant Yet Serializable Execution of Transaction Programs
Brecht Vandevoort, Alan Fekete, Bas Ketsman +2
We propose a theory that can determine the lowest isolation level that can be allocated to each transaction program in an application in a mixed-isolation-level setting, to guarant…
Instance-Optimal Acyclic Join Processing Without Regret: Engineering the Yannakakis Algorithm in Column Stores
Liese Bekkers, Frank Neven, Stijn Vansummeren +1
Acyclic join queries can be evaluated instance-optimally using Yannakakis' algorithm, which avoids needlessly large intermediate results through semi-join passes. Recent work propo…
Schema Matching with Large Language Models: an Experimental Study
Marcel Parciak, Brecht Vandevoort, Frank Neven +2
Large Language Models (LLMs) have shown useful applications in a variety of tasks, including data wrangling. In this paper, we investigate the use of an off-the-shelf LLM for schem…
Measuring Approximate Functional Dependencies: a Comparative Study
Marcel Parciak, Sebastiaan Weytjens, Niel Hens +3
Approximate functional dependencies (AFDs) are functional dependencies (FDs) that "almost" hold in a relation. While various measures have been proposed to quantify the level to wh…
