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…
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…
When View- and Conflict-Robustness Coincide for Multiversion Concurrency Control
Brecht Vandevoort, Bas Ketsman, Frank Neven
A DBMS allows trading consistency for efficiency through the allocation of isolation levels that are strictly weaker than serializability. The robustness problem asks whether, for…
Detecting Robustness against MVRC for Transaction Programs with Predicate Reads
Brecht Vandevoort, Bas Ketsman, Christoph Koch +1
The transactional robustness problem revolves around deciding whether, for a given workload, a lower isolation level than Serializable is sufficient to guarantee serializability. T…
Robustness against Read Committed for Transaction Templates with Functional Constraints
Brecht Vandevoort, Bas Ketsman, Christoph Koch +1
The popular isolation level Multiversion Read Committed (RC) trades some of the strong guarantees of serializability for increased transaction throughput. Sometimes, transaction wo…
Robustness against Read Committed for Transaction Templates
Brecht Vandevoort, Bas Ketsman, Christoph Koch +1
The isolation level Multiversion Read Committed (RC), offered by many database systems, is known to trade consistency for increased transaction throughput. Sometimes, transaction w…
