Schema-Based Query Optimisation for Graph Databases
Chandan Sharma, Pierre Genevès, Nils Gesbert +1
Recursive graph queries are increasingly popular for extracting information from interconnected data found in various domains such as social networks, life sciences, and business a…
Efficient Enumeration of Recursive Plans in Transformation-based Query Optimizers
Amela Fejza, Pierre Genevès, Nabil Layaïda
Query optimizers built on the transformation-based Volcano/Cascades framework are used in many database systems. Transformations proposed earlier on the logical query dag (LQDAG) d…
Distributed Evaluation of Graph Queries using Recursive Relational Algebra
Sarah Chlyah, Pierre Genevès, Nabil Layaïda
We present a system called Dist--RA for the distributed evaluation of recursive graph queries. Dist--RA builds on the recursive relational algebra and extends it with evaluat…
