In this paper, we address the problem of processing reverse top-k queries in a parallel and distributed setting. Given a database of objects, a set of user preferences, and a query object q, the ...

This was a high-stakes implementation of advanced data pipelines designed with zero tolerance for data inconsistency or ...

For instance, in the above example, parallel databases with simple federation capabilities would still use the execution strategy A. This means 695 million rows would need to be transferred through ...

Skyline queries are capable of retrieving interesting points from a large data set according to multiple criteria. Most work on skyline queries so far has assumed a centralized storage, whereas in ...

This paper proposes a Beowulf cluster for fast query processing by distributing the database horizontally over nodes through a load balancing act. A mathematical model is proposed to optimally ...

Recent advances in graphics processing units (GPUs) have opened a new frontier in query processing and database systems. Leveraging the massively parallel architecture of GPUs, modern database ...

A distributed, modular, HTAP database, TiDB is designed to scale compute and storage capacity horizontally and flexibly to adapt to different workloads, while also serving as a “single source of ...
