DESCRIPTION:Data Science at Scale: Scaling Up by Scaling Down and Out (to Disk)
URL;VALUE=URI:https://www.csa.iisc.ac.in/newweb/event/112/data-science-at-scale-scaling-up-by-scaling-down-and-out-to-disk/
SUMMARY:The standard solution to scaling applications to massive data is scale-out, i.e., use more computers or RAM. This talk presents my work on complementary techniques: scaling down, i.e., shrinking data to fit in RAM, and scaling to disk, i.e., organizing data on disk so that the application can still run fast. I will describe new compact and I/O-efficient data structures and their applications in stream processing, computational biology, and storage.
<br>
Concretely, I show how to bridge the gap between the worlds of external memory and stream processing to perform scalable and precise real-time event-detection on massive streams. I show how to shrink genomic and transcriptomic indexes by a factor of two while accelerating queries by an order of magnitude compared to the state-of-the-art tools. I show how to improve file-system random-write performance by an order of magnitude without sacrificing sequential read/write performance.
