The goal of the benchmark tests are to highlight the parallel aspects of VXQuery. The tests need to show how VXQuery scales. In addition, other queries may be added to highlight our specific speed improvements or where improvements can still be made. At first we want to show how the system works with parallel queries. We focus on three types of queries: filtering, aggregation and nested loops (join).
For these three queries the following scaling tests will be completed: scale up and speed up. * Scale up keeps the number of nodes in the cluster constant and increases the data set in each successive test. * Speed up keeps the data set size constant and increases the number of nodes processing the data in each successive test. ( http://en.wikipedia.org/wiki/Speedup) Still working on the specific queries for our GHCN daily data, but you can see the draft version here: https://svn.apache.org/repos/asf/incubator/vxquery/trunk/vxquery/vxquery-benchmark/src/main/resources/noaa-ghcn-daily/queries/
