Opinion Pieces of the BTW 2025 Workshop On Advances in Cloud Data Management

Abstract The BTW 2025 Workshop on Advances in Cloud Data Management explored recent developments and future directions in cloud data management. Speakers discussed advancements in data warehousing, query optimization, and data pipeline architectures to enhance performance and efficiency in cloud environments. The workshop also addressed challenges in managing data for modern software architectures, such as event-driven microservices, and the complexities of decomposing database systems. Additionally, presentations covered the potential of serverless computing for cost-efficient data processing and the importance of fine-grained access control for data governance. For this special issue of Datenbank-Spektrum , we asked the speakers of the workshop to extend the abstracts of their talks by, for example, including their opinions on the future of data management systems in the cloud. Consequently, we titled this collection of articles Opinion Pieces . These articles are not peer-reviewed and present the authors’ individual viewpoints. Nine speakers submitted articles for publication. Articles are sorted by the last name of the first author. For editorial reasons, there is only one bibliography instead of individual ones, which we would have preferred. We hope that the idea of publishing opinion pieces will receive positive attention and that this style of submission may be replicated in other areas of the spectrum of databases. We want to thank all speakers again for delivering highly interesting talks at the BTW workshop and for submitting these opinion pieces for publication.
