Towards Anticipatory Databases Through Shared Data and Workload Semantics

Farzaneh Zirak, Kasper Overgaard Mortensen, Farhana Choudhury +1

Database management systems increasingly serve dynamic and exploratory workloads, yet many of their decisions still rely on low-level signals such as recency, frequency, and addres…

Testing the Robustness of Learned Index Structures

Matthias Bachfischer, Renata Borovica-Gajic, Benjamin I. P. Rubinstein

While early empirical evidence has supported the case for learned index structures as having favourable average-case performance, little is known about their worst-case performance…
