Since the 1970's, database
systems have been "compute-centric". When a computation needs the
data, it requests the data, and the data are
pulled through the system. This is problematic for two reasons.
requests for data naturally incur high latency as the data are pulled
through the memory hierarchy, and second, it makes it difficult or
impossible for multiple queries or operations that are interested in
the same data to amortize the bandwidth and latency costs associated
with their data access.
This talk describes a purely-push based, research prototype analytic
database system called DataPath that is being developed at Rice
University and the University of Florida. DataPath is "data
centric". In DataPath, queries do not request data.
Instead, data are
automatically pushed onto processors, where they are then processed by
any interested computation. The talk will describe a
multi-terabyte benchmark of DataPath which argues that "data centric"
design makes for
a very lean and fast database system.
Chris Jermaine is an
associate professor at Rice University where he
studies statistical databases. Prior to coming to Rice in 2009, Chris
was at the University of Florida. Chris is the recipient of a
Alfred P. Sloan Foundation Research Fellowship, a National Science
Foundation CAREER award, and a 2007 ACM SIGMOD Best Paper Award. In his
spare time, Chris enjoys running, gardening, and outdoor activities
such as hiking, climbing, and whitewater boating. In one particular
exploit, Chris and his wife floated a whitewater raft (home-made from
scratch using a sewing machine, glue, and plastic) over 100 miles down
the Nizina River (and beyond) in Alaska.
