Robust Data Systems Tuning


BU faculty members Manos Athanassoulis and Evimaria Terzi will work on building a new robust tuning framework for LSM-based data systems that will allow to deploy and effectively tune data systems even when the workload information is inaccurate or noisy. This approach has the potential to revolutionize tuning and deployment of cloud-based data systems, which face volatility in resources availability and workload as multiple applications are collocated on shared virtualized infrastructure. The proposed paradigm addressed the observed workload uncertainty by (re-)formulating the tuning problem as a min-max optimization problem that seeks to find the best tuning for the worst-case workload within an uncertainty region. “The proposed robust tuning paradigm will also improve the collective understanding of robust tuning for data systems in general, a useful tool as new applications face increased workload volatility,” the team wrote.
