Title: | Processing of multiple long-running queries in large-scale geo-data repositories | Authors: | Tok, W.H. Bressan, S. |
Issue Date: | 2006 | Citation: | Tok, W.H.,Bressan, S. (2006). Processing of multiple long-running queries in large-scale geo-data repositories.

ScholarBank@NUS Repository. | Abstract: | One of the main challenges of large-scale information mediation and warehousing is the efficient and resourceeffective processing of continuous queries. Continuous queries monitor streams of incoming data and produce results on-the-fly. They are usually long-running, yet need to be removed from the system when they become obsolete. We present a framework and the corresponding algorithms and data-structures for the efficient evaluation of multiple longrunning spatial queries over unbounded streams of spatial data and the management of obsolete queries. Using both real-life and synthetic datasets and workloads, we show that our proposed approach achieves significant improvements over standard approaches.
