An Efficient Implementation of Query/Advertise
Abstract
It is demonstrated how a publish/subscribe system can be extended to support the efficient distribution of queries to relevant sites. Queries are encoded as messages that are efficiently distributed to sites providing advertisements, which are special queries that describe the data sets available at each site. An important aspect of this research is to provide a sufficiently powerful language for expressing queries. It is shown how adding a form of constraint to the system as a first class class object can support expressive queries. A query system is constructed on top of the Siena wide-area publish/subscribe system, and it is shown how to optimize the distribution of queries.
