This repository contains the source code of Graph Engine and its graph query language -- Language Integrated Knowledge Query (LIKQ).

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.

LIKQ is a versatile graph query language on top of Graph Engine that combines the capability of fast graph exploration with the flexibility of lambda expression. Server-side computations can be expressed in lambda expressions, embedded in LIKQ, and executed server side during graph traversal. LIKQ is powering Academic Graph Search API, part of Microsoft Cognitive Services.

Getting started with Graph Engine

Downloads

Recommended: Install by searching for "Graph Engine" in the Visual Studio UI under Tools > Extensions and Updates

It can also be downloaded from Visual Studio Gallery.

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

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

Building for Windows

Install Visual Studio 2017, making sure to include the following workloads and components:

.NET desktop development
Desktop development with C++
cmake
.NET Core SDK 2.0 or above

The Windows build will generate multi-targeting nuget packages for all the available modules. Run tools/build.ps1 with powershell to setup a workspace folder build, and build using cmake.

The Linux native assemblies will be automatically packaged (pre-built at lib), allowing the Windows build to also work for Linux .Net Core.

Nuget packages will be built and put at build/GraphEngine**._version_.nupkg. The folder build/ 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 the 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.

Because 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 build/GraphEngine**._version_.nupkg. The folder build/ 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.
