Third International Workshop on Composable Data Management Systems, 2025

Workshop Venue: London, United Kingdom - Co-located with VLDB 2025

Workshop Date: 5th September 2025

Call For Lightning Talk Proposals

The aim of the CDMS workshop is to bring together database researchers, practitioners, developers and users from academia, business and industry to discuss and explore the area of building database management systems with emphasis on composability and reusability. The aim of the CDMS workshop is to bring together database researchers, practitioners, developers and users from academia, business and industry to discuss and explore the area of building database management systems with emphasis on composability and reusability. The second edition of the workshop invites proposals for lightning talks on topics that are relevant to the theme of the workshop. Lightning talks give attendees of the workshop an opportunity to present work at any phase of the research process. This track allows the speakers to garner feedback and gain exposure. The duration of the lightning talks will be limited to 5 minutes.

The list of topics of interest are as follows (the list is by no means exhaustive):

  • Unified data models that cater to a wide range of data shapes, types and use cases
  • Standard language support. Support for both deferred mode execution (SQL) and eager/interactive development (e.g. REPL, host language execution (Python/PyTorch)) Uniform operation semantics for interoperability across systems
  • Engineering modular DM system components like parser, query optimizer, execution engine and transaction coordinator
  • Query Processing and Optimization Techniques for composable DM systems
  • Query Execution Techniques for composable DM systems
  • Standardization of exchange protocols and API for different modules of DM systems
  • Open source efforts for sharing composable DM modules
