Database Systems on Evolving Hardware

The architecture and algorithms of database and data-intensive systems in general have been built around the properties of existing hardware technologies. Many of the elementary design and algorithmic assumptions have been made to compensate for technological weaknesses of 20-30 years old hardware characteristics.

Over the last decade we witnessed several major hardware developments, all of which will be dominant trends for the next decade [1]:
- many-core CPUs - 1000 cores per chip by 2022 [1]
- growing RAM volumes - more than 128 TB RAM per server by 2022 [1]
- increasing interconnect bandwidth - memory: 2.5 TB/s, I/O: 250 GB/s by 2022 [1]
- better I/O technologies - fast 1TB Flash chips and Non-Volatile Memories with read performance similar to that of DRAM
- use of Non-Volatile Memories and evoloving memory heirarchies


Central Reseach Question
What is the impact on the architecture, algorithms, performance and energy efficiency of data-intensive systems.
