Graph Engine - Open Source

Microsoft Graph Engine is a distributed in-memory data processing engine, underpinned by a strongly-typed in-memory key-value store and a general distributed computation engine.

This repository contains the source code of Graph Engine and its graph query language -- Language Integrated Knowledge Query (LIKQ). LIKQ is a versatile graph query language on top of Graph Engine. It combines the capability of fast graph exploration and the flexibility of lambda expression: server-side computations can be expressed in lambda expressions, embedded in LIKQ, and executed on the server side during graph traversal. LIKQ is powering Academic Graph Search API, which is part of Microsoft Cognitive Services.

Downloads

Graph Engine is regularly released with bug fixes and feature enhancements.

You can install Graph Engine Visual Studio Extension by searching "Graph Engine" in Visual Studio Extensions and Updates (recommended). It can also be downloaded from Visual Studio Gallery.

NuGet packages Graph Engine Core and LIKQ are available in the NuGet Gallery.

How to Contribute

Pull requests, issue reports, and suggestions are welcome.

If you are interested in contributing to the code, please fork the repository and submit pull requests to the master branch.

Please submit bugs and feature requests in GitHub Issues.

Building for Windows

Install Visual Studio 2017. Install Windows 10 SDK (10.0.15063.0) for Desktop C++. The Windows build will generate multi-targeting nuget packages for all the available modules, so make sure you also install .NET Core SDK 2.0. Additionally, to build the python FFI packages, make sure you install a python3 environment, and the Visual Studio 2015 C++ toolchain. All these dependencies can be installed with the visual studio 2017 installer (yes, including MSVC 2015 stuff).

Run tools/build.ps1 with powershell.

The Linux native assemblies will be automatically packaged, so the Windows build will also work for Linux .Net Core.

Nuget packages will be built and put at bin/GraphEngine**._version_.nupkg. The folder bin/ will be registered as a local NuGet repository and the local package cache for GraphEngine.** will be cleared. After the packages are built, you can run dotnet restore to use the newly built package.

Building for Linux

Install libunwind8, g++, cmake and libssl-dev. Install dotnet package following the official guide.

Execute tools/build.sh.

The Windows native assemblies will be automatically packaged, so the Linux build will also work for Windows .Net Core. Note, as targeting .Net Framework is not supported, the packages built on Linux are not equivalent to their Windows builds, and will only support .Net Core.

Nuget packages will be built and put at bin/GraphEngine**._version_.nupkg. The folder bin/ will be registered as a local NuGet repository and the local package cache for GraphEngine.Core will be cleared. After the packages are built, you can run dotnet restore to use the newly built package.

Note: the build script currently only supports Ubuntu 16.04.
