## What it is
Microsoft Graph Engine is a distributed in-memory data processing engine built on a strongly-typed in-memory key-value store and a general-purpose distributed computation framework. It includes LIKQ, a graph query language that executes lambda-expression-based server-side computations during graph traversal.

## Use cases
- query large graphs with lambda expressions server-side
- build distributed in-memory graph applications in .NET
- run fast graph traversal over an in-memory key-value store
- process graph data across a cluster of machines
- implement custom graph analytics with server-side computation

## When to choose
- you need distributed in-memory graph processing on .NET
- you want server-side lambda-based graph queries (LIKQ)
- you are doing research on graph engines or graph query languages

## When to avoid
- you need a production-supported database from Microsoft (it is a research project)
- you need a general-purpose persistent graph database with mature tooling
- your stack is not .NET/C#

## Facets
- artifact type: framework
- maturity: maintenance
- function: database, search-engine, serialization, rpc, concurrency
- domain: databases, microservices, big-data, graph-processing, developer-tools
- platform: windows, dotnet, cross-platform
