DESCRIPTION:Speaker: Manos Athanassoulis\nhosted by Bernd Bickel\nAbstract:
  Business and science create an increasing amount of digital data every da
 y\; these ever growing data collections require analytical workflows that 
 support fast ingestion\, and fast read queries\; in other words\, data sys
 tems need to support increasingly heterogeneous workloads\, that weave rea
 d-mostly analytical operations and update-heavy transactional operations\,
  into hybrid transactional/analytical processing workloads. In this talk I
  will present a path towards building access methods for this new set of w
 orkloads. As the design goals typically entail to reduce read latency\, up
 date latency\, and space utilization\, I attack the problem by studying th
 e trade-offs between these design goals\, and I propose solutions that bal
 ance the trade-offs through modeling and optimization. I will use this met
 hodology to build access methods for modern key-value stores\, basic colum
 n storage\, and to present how to perform access path selection in light o
 f the changes in workloads and hardware. I will conclude with abstracting 
 the common concepts of access method designs\, and propose a path towards 
 data access methods for the new era.
