This is the repository for the current Hyrise version, which has been rewritten from scratch. The new code base is easier to setup, to understand, and to contribute to. As of now, not all features of the old version are supported yet - we are working on that.

Papers that were published before October 2017 were based on the previous version of Hyrise, which can be found here.

Have a look at our contributor guidelines

You can find definitions of most of the terms and abbreviations used in the code in the glossary. If you ca not find something that you are looking for, feel free to open an issue.

The Step by Step Guide is a good starting point to get to know Hyrise.

You can install the dependencies on your own or use the install.sh script (recommended) which installs all of the therein listed dependencies and submodules. The install script was tested under macOS (brew) and Ubuntu 17.04/17.10 (apt-get).

See dependencies for a detailed list of dependencies to use with brew install or apt-get install, depending on your platform. As compilers, we generally use the most recent version of clang and gcc (Linux only). Please make sure that the system compiler points to the most recent version or use cmake (see below) accordingly. Older versions may work, but are neither tested nor supported.

To get all dependencies of Hyrise in a docker image, run

docker-compose build

You can start the container via

docker-compose run --rm hyrise

Inside of the container, run ./install.sh to download the required submodules. :whale:

It is highly recommended to perform out-of-source builds, i.e., creating a separate directory for the build. Advisable names for this directory would be cmake-build-{debug,release}, depending on the build type. Within this directory call cmake .. to configure the build. Subsequent calls to CMake, e.g., when adding files to the build will not be necessary, the generated Makefiles will take care of that.

CMake will default to your system's default compiler. To use a different one, call like cmake -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ .. in a clean build directory.

Simply call make -j*, where * denotes the number of threads to use.

Usually debug binaries are created. To configure a build directory for a release build make sure it is empty and call CMake like cmake -DCMAKE_BUILD_TYPE=Release

./scripts/lint.sh (Google's cpplint is used which needs python 2.7)

./scripts/format.sh (clang-format is used)

Calling make hyriseTest from the build directory builds all available tests. The binary can be executed with ./<YourBuildDirectory>/hyriseTest. Note, that the tests/sanitizers/etc need to be executed from the project root in order for table files to be found.

./scripts/coverage.sh <build dir> will print a summary to the command line and create detailed html reports at ./coverage/index.html

Supports only clang on MacOS and only gcc on linux

make hyriseSanitizers will build Hyrise's tests with enabled AddressSanitizer and Undefined Behavior options. Execute ./<YourBuildDirectory>/hyriseSanitizers from the project root to run the tests with enabled sanitization. It will fail on the first detected error and will print a summary. To convert addresses to actual source code locations, make sure llvm-symbolizer is installed (included in the llvm package) and is available in $PATH. To specify a custom location for the symbolizer, set $ASAN_SYMBOLIZER_PATH to the path of the executable. This seems to work out of the box on macOS - If not, make sure to have llvm installed. The binary can be executed with LSAN_OPTIONS=suppressions=asan-ignore.txt ./<YourBuildDirectory>/hyriseSanitizers.

When trying to optimize the time spent building the project, it is often helpful to have an idea how much time is spent where. scripts/compile_time.sh helps with that. Get usage instructions by running it without any arguments.
