Implement the avg function and constructor in src/JoinQuery.cpp. See the corresponding header include/JoinQuery.hpp for documentation of this function. All solutions that compute correct results and achieve a time measurement better than 15 seconds on the leaderboard will be accepted for the bonus.

The performance evaluation will run the binary compiled from main.cpp so that the avg query is run for multiple market segments on a TPC-H dataset with scale factor 1. The overall runtime from start to end is measured.

You can use the test provided in test/JoinQuery.cpp to check if your implementation works correctly.

When you do performance tuning, you may use and extend the benchmark suite in bench/JoinQuery.cpp.

Build

A configuration file is provided to build this project with CMake. This allows you to build the project in the terminal but also provides the option to use Jetbrains CLion or Microsoft Visual Studio and other IDEs.

Building from Terminal: Start in the project directory.

mkdir -p build/debug
cd build/debug
cmake -DCMAKE_BUILD_TYPE=Debug ../..
make

This creates the binaries test_all, bench and main.
