I Don&#39t Want to be the Mitt Romney of Databases

What can I say? Yes, I helped build a database management system (DBMS) for the &#34one percent.&#34 This previous system (H-Store) is able to get up to 40x higher throughput over traditional, disk-oriented DBMSs for on-line transaction processing workloads. But getting this great performance requires a significant upfront deployment cost (e.g., application rewriting, pre-partitioning). It is also unable to perform non-trivial analysis operations without the use of a separate data warehouse, which further increases costs and overhead. This makes a DBMS like ours accessible to only those organizations with ample resources.

In this talk, I outline our vision for a new distributed DBMS (codenamed &#34The Brain&#34) that we are building at CMU that is truly for the 99%. It will enable any application to get the same kind of performance as a specialized system like H-Store without any expensive setup or maintenance. The crux of the system is to employ machine learning techniques to support the efficient execution of hybrid workloads (transactions + analytics) through intelligent pre-fetching and automatic partitioning/tuning. In essence, our new DBMS is able to learn about how an application uses the database without any human intervention and reconfigure itself accordingly.
