Robust Query Processing in the Cloud (Dagstuhl Seminar 24101)

Authors: Goetz Graefe, Allison Lee, and Caetano Sauer

Published in: Dagstuhl Reports, Volume 14, Issue 3 (2024)


Abstract
The Dagstuhl Seminar on "Robust Query Processing in the Cloud" (24101), held from March 3 to March 8, 2024, brought together researchers from academia and industry to discuss robustness in database management systems. This seminar was a continuation of previous seminars on the topic of Robust Query Processing, where we focused in particular on cloud computing and also discussed aspects that have not been addressed by the previous instances of the seminar. This article summarizes the main discussion topics, and presents the summary of the outputs of five working groups that discussed: i) robustness benchmarking, ii) economics of query processing in the cloud, iii) storage architectures, iv) out-of-memory query operators, and v) indexing for data warehousing.

Database Architectures for Modern Hardware (Dagstuhl Seminar 18251)

Authors: Peter A. Boncz, Goetz Graefe, Binsheng He, and Kai-Uwe Sattler

Published in: Dagstuhl Reports, Volume 8, Issue 6 (2019)


Abstract
The requirements of emerging applications on the one hand and the trends in computing hardware and systems on the other hand demand a fundamental rethinking of current data management architectures. Based on the broad consensus that this rethinking requires expertise from different research disciplines, the goal of this seminar was to bring together researchers and practitioners from these areas representing both the software and hardware sides and to foster cross-cutting architectural discussions. The outcome of this seminar was not only an identification of promising hardware technologies and their exploitation in data management systems but also a set of use cases, studies, and experiments for new architectural concepts.

Database Workload Management (Dagstuhl Seminar 12282)

Authors: Shivnath Babu, Goetz Graefe, and Harumi Anne Kuno

Published in: Dagstuhl Reports, Volume 2, Issue 7 (2013)


Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 12282 "Database Workload Management". Dagstuhl Seminar 12282 was designed to provide a venue where researchers can engage in dialogue with industrial participants for an in-depth exploration of challenging industrial workloads, where industrial participants can challenge researchers to apply the lessons-learned from their large-scale experiments to multiple real systems, and that would facilitate the release of real workloads that can be used to drive future research, and concrete measures to evaluate and compare workload management techniques in the context of these workloads.

Abstract
The 2012 Dagstuhl 12321 Workshop on Robust Query Processing, held from 5--10 August 2012, brought together researchers from both academia and industry to discuss various aspects of robustness in database management systems and ideas for future research. The Workshop was designed as a sequel to an earlier Workshop, Dagstuhl Workshop 10381, that studied a similar set of topics. In this article we summarize some of the main discussion topics of the 12321 Workshop, the results to date, and some open problems that remain.

08281 Executive Summary – Software Engineering for Tailor-made Data Management

Authors: Sven Apel, Don Batory, Goetz Graefe, Gunter Saake, and Olaf Spinczyk

Published in: Dagstuhl Seminar Proceedings, Volume 8281, Software Engineering for Tailor-made Data Management (2008)


Abstract
Tailor-made data management software (DMS) is not only important in the field of embedded systems. DMS that incorporates only features that are required bear the potential to strip down the code base and to improve reliability and maintainability. In the past 20 years several new technologies have emerged that aim at lean, efficient, and well-structured software, which should also be applicable to DMS. In the Dagstuhl Seminar ``Software Engineering for Tailor-made Data Management'', July 6h to July 11th, 2008, 29 researchers from 7 countries discussed the development, application, and assessment of these new technologies in the context of DMS.

B-tree indexes for high update rates

Authors: Goetz Graefe

Published in: Dagstuhl Seminar Proceedings, Volume 5421, Data Always and Everywhere - Management of Mobile, Ubiquitous, Pervasive, and Sensor Data (2006)


Abstract
In some applications, data capture dominates query processing. For example, monitoring moving objects often requires more insertions and updates than queries. Data gathering using automated sensors often exhibits this imbalance. More generally, indexing streams apparently is considered an unsolved problem. For those applications, B-tree indexes are reasonable choices if some trade-off decisions are tilted towards optimization of updates rather than of queries. This paper surveys techniques that let B-trees sustain very high update rates, up to multiple orders of magnitude higher than tradi-tional B-trees, at the expense of query processing performance. Perhaps not surprisingly, some of these techniques are reminiscent of those employed during index creation, index rebuild, etc., while others are derived from other well known technologies such as differential files and log-structured file systems.
