Data mining on an OLTP system (nearly) for free

Abstract
This paper proposes a scheme for scheduling disk requests thattakes advantage of the ability of high-level functions to operatedirectly at individual disk drives. We show that such a schememakes it possible to support a Data Mining workload on an OLTPsystem almost for free: there is only a small impact on the throughputand response time of the existing workload. Specifically, weshow that an OLTP system has the disk resources to consistentlyprovide one third of its sequential bandwidth to ...
