I/O and Data Seminar Series: Revisiting Databases for Scale Up Data Management

Title of Presentation: “Revisiting Databases for Scale Up Data Management”

Presented by: Jay Lofstead, Sandia National Laboratory

Speaker’s Abstract:
Traditional relational databases were rejected for data management for scale up computing due to overhead issues. Instead, we have adopted custom file formats with minimal overhead. With the shifting technology landscape including data movement being the new bottleneck (rather than storage device latencies), revisiting how much databases, including newer NoSQL databases, can be useful in scale up computing. Data indexing to accelerate data selection and robust resilience mechanisms inherent in transactional systems offer features that are still attractive for scale up computing. This talk describes initial efforts investigating using these technologies for scale up computing.
