Query Rewriting for Incremental Continuous Query Evaluation in HIFUN

Petros Zervoudakis et al.

Summary: This paper presents a methodology based on the HIFUN language and corresponding algorithms for incremental evaluation of continuous queries, effectively processing the most recent data batch by exploiting already computed information. The generic algorithm is implemented in both SQL and MapReduce using SPARK, demonstrating the effectiveness in query answering efficiency. By leveraging the formal query rewriting methods of HIFUN, the computational cost can be further reduced, adding another layer of query optimization to the implementation.
