Efficient Distributed Cq Processing Using Peers

ABSTRACT. In this paper, we propose a framework called CQ-Buddy, for supporting distributed continuous query CQ processing system based on Peer-to-Peer P2P technology. Working on the basis of peer heterogeneity, peers in a CQ-Buddy network help one another by sharing query workload and providing data.

Aggregate Query Processing Definition

Clustering spatial networks for aggregate query processing . in the original problem definition given in Section 2.1.3, the number K of parts is not known in advance. Thus, they use a partitioning algorithm based on RB with ratio-cut heuristic in order to create a number of parts, each with a size less than or equal to the disk page size .

Aqp Connecting Approximate Query Processing With

May 27, 2018 In the past, the database community has proposed two separate ideas, sampling-based approximate query processing AQP and aggregate precomputation AggPre such as data cubes, to address this challenge. In this paper, we argue for the need to connect these two separate ideas for interactive analytics.

Scalable Distributed Aggregate Computations Through

Abstract. Computing aggregates over distributed data sets constitutes an interesting class of distributed queries. Recent advances in peer-to-peer discovery of data sources and query processing techniques have made such queries feasible and potentially more frequent. The concurrent execution of

Improving Search In Peertopeer Networks

network, nodes spend processing resources i.e., cycles to forward the query, process it, etc, and bandwidth to send and receive messages. The main cost of queries are there-fore bandwidth and processing. Since the cost of a query is not incurred at any single node in the network, it makes sense to discuss costs in aggregate i.e., overall the ...

Supporting Ranked Search In Parallel Search Cluster

querying peer. The local aggregate information are merged into the global aggregate information at the querying peer, and are distributed in the cluster. Next, each participating peer evaluates the query over the indexes it stores, ranks its query results locally, and sends the locally ranked query results back to the querying peer.

Efficient Approximate Topk Query Algorithm Using

query processing has been also studied in peer-to-peer environments. The KLEE system Michel et al. 2 addressed this problem, where distributed aggregation queries are processed based on index lists located at isolated sites. KLEE assumes no random accesses are made to index lists located at each peer.

Distributed Online Aggregations Proceedings Of The Vldb

Aug 01, 2009 In many decision making applications, users typically issue aggregate queries. To evaluate these computationally expensive queries, online aggregation has been developed to provide approximate answers with their respective confidence intervals quickly, and to continuously refine the answers. In this paper, we extend the online aggregation technique to a distributed context where

Designing A Superpeer Network Stanford University

Abstract A super-peeris a node in a peer-to-peer network that operates both as a server to a set of clients, and as an equal in a network of super-peers. Super-peer networks strike a balance between the inherent efciency of centralized search, and the autonomy, load balancing and robustness to attacks provided by distributed search.
