CompoDB:ADemonstration of Modular Data Systems in Practice
The increasing demand for specialization in data management systems (DMSes) has driven a shift from monolithic architectures to modular, composable designs. This approach enables the reuse and integration of diverse components, providing exibility to tailor systems for speci c workloads. In this demonstration, we present CompoDB, a framework for composing modular DMSes using standardized interfaces for query parsers, optimizers, and execution engines. CompoDB includes built-in benchmarking functionality to evaluate the performance of DMS compositions by systematically measuring trade-o s across con gurations, includ ing runtime di erences and intermediate query plans. Attendees will interact with CompoDB through an interactive GUI that allows them to compose custom DMSes, execute queries, and observe detailed performance metrics in real time. Altogether, this demonstration highlights the practicality of modular DMS architectures and their potential for optimizing data management solutions for specific workloads.
