Efficient and Semantic OLAP Aggregation Queries in a Peer to Peer Network

This paper presents TrackerCache system - a Peer to Peer (P2P) system for efficient serving OLAP queries and aggregation of data cubes in distributed data sharing system. TrackerCache system provides a central component called tracker, which acts as a directory, keeping track of all submitted queries and a list of peers caching their results. The key idea is to enable peers to share their local caches, to form an efficient and semantic distributed cache sharing system. For this issue, a query forwarding policy is introduced. To face inconsistent information in the client side cache, we proposed a knowledge replacement policy based on Binary Decision Tree (BDT) to evict unwanted data. Then, we present experimental evaluations to demonstrate the efficiency of our proposed solutions.
