  Aggregation and query processing

  Aggregation and query processing From the perspective of query processing (QP) aggregation can be both a costly operation and an operation whose placement has an important impact on query performance Aggregation generally computes an aggregated value Vector aggregation is costly compared to scalar aggregation as rows must be grouped together to obtain the aggregated result

  Aggregate Vs SQL Query in Server Action

  20 11 2019Hi Marc Jason Francia Yes if the only attribute you use from the Aggregate's sources is the City Id the platform will optimize the query executed to only fetch the Id column If you only use the first record of the Aggregate's output list you may need to use the Max Records property of the Aggregate to restrict the query to only return one record

  Clustering spatial networks for aggregate query

  In spatial networks clustering adjacent data to disk pages is highly likely to reduce the number of disk page accesses made by the aggregate network operations during query processing For this purpose different techniques based on the clustering graph model are proposed in the literature In this work we show that the state-of-the-art clustering graph model is not able to correctly capture
