This repository contains the source code of Microsoft 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-purpose distributed computation engine.
LIKQ is a versatile graph query language built atop Graph Engine. It combines the capability of fast graph exploration with the flexibility of lambda expressions. Server-side computations can be expressed in lambda expressions, embedded in LIKQ, and executed on the Graph Engine servers during graph traversal.
The main version number is bumped to 3.0 to reflect the recent toolchain updates.
- .NET 6.0 is now the mainly supported target framework
- Visual Studio 2022 is supported
One goal of Graph Engine 3.0 is to bring the system up to date and make it slimmer. Some obsolete or outdated modules and tools have been moved to the Unsupported directory and removed from the main build pipeline.
Recommended operating system: Windows 10 or Ubuntu 20.04.
Download and install Visual Studio with the following "workloads" and "individual components" selected:
- The ".NET desktop development" and "Desktop development with C++" workloads.
- The ".NET Portable Library targeting pack" individual component.
Open a PowerShell window, run tools/build.ps1 for building the NuGet packages.
The script has been tested on Windows 10 (21H2) with Visual Studio 2022.
Install g++, cmake, and libssl-dev. For example, on Ubuntu, simply run
sudo apt update && sudo apt install g++ cmake libssl-devInstall .NET SDK x64 6.0 and run:
bash tools/build.shThe build script has been tested on Ubuntu 20.04 with g++ 9.4.0.
You can find the built NuGet packages build/GraphEngine**._version_.nupkg in
the build folder. In the building process, the build directory has been
registered as a local NuGet repository and the local package cache for
GraphEngine.Core has been cleared. After the packages are built, run dotnet restore to use the newly built packages.
Go to the samples/Friends folder, execute dotnet restore and dotnet run to
run the sample project.
