This talk focuses on emerging challenges and opportunities related to the scalability of data access in the context of increasing convergence between big data analytics and high performance computing approaches. It emphasizes the importance of scalability not only from the perspective of performance, but also resource utilization. Several broader patterns are used to illustrate this point: (1) versioning-based data models; (2) on-demand broadcast; (3) wide transformations. The talk concludes with several open questions that reveal exploratory future work.
