Yiyan Li, Guanli Liu, Renata Borovica-Gajic +6
Database tuning is critical for achieving high performance in modern database management systems (DBMSs). Existing methods typically optimize a single component---knobs, indexes, o…
Efficient Cost Modeling of Space-filling Curves
Guanli Liu, Lars Kulik, Christian S. Jensen +2
A space-filling curve (SFC) maps points in a multi-dimensional space to one-dimensional points by discretizing the multi-dimensional space into cells and imposing a linear order on…
A Lazy Approach for Efficient Index Learning
Guanli Liu, Lars Kulik, Xingjun Ma +1
Learned indices using neural networks have been shown to outperform traditional indices such as B-trees in both query time and memory. However, learning the distribution of a large…
