Introduction

Trying to get the DistributedHashtable sample working with a Trinity GE cluster.

This is what came out of the discussion in microsoft/GraphEngine#285. Thanks to TaviTruman for most of the code to get this working.

This example does not utilize a config. In a production environment you'll probably want to use a proper XML config and load it with TrinityConfig.Load().

Build and Test

Manual

Here are the steps to setup a Trinity GE cluster with three nodes, listening on 127.0.0.1:700[0-2]. The last step runs a simple client and connects to the cluster.

• Clone GraphEngine: git clone https://github.com/microsoft/GraphEngine.git
• Build GraphEngine: ./GraphEngine/tools/build.sh
• Build the client: dotnet build DistributedHashtable/DHT.GE.Client
• Build the server: dotnet build DistributedHashtable/DHT.GE.Server
• Run 1st node: dotnet run --project DistributedHashtable/DHT.GE.Server --no-build -- 127.0.0.1:7001
• Run 2nd node: dotnet run --project DistributedHashtable/DHT.GE.Server --no-build -- 127.0.0.1:7002
• Run head node: dotnet run --project DistributedHashtable/DHT.GE.Server --no-build -- 127.0.0.1:7000,127.0.0.1:7001,127.0.0.1:7002
• Run client: dotnet run --project DistributedHashtable/DHT.GE.Client --no-build -- 127.0.0.1:7000

Docker

You can build the docker image locally with docker build -t trinity . Then you can fire up a trinity instance like this:

docker run --rm -it -p 7000:7000 trinity dotnet run --no-build --project DistributedHashtable/DHT.GE.Server -- 127.0.0.1:7000

This assumes you want to run a server node and host the service on port 7000.

Another option is to use docker-compose:

• Start the cluster: docker-compose up
• Connect with a client (directly with dotnet run or using docker):
  • dotnet run --no-build --project DistributedHashtable/DHT.GE.Client -- 127.0.0.1:7000 OR
  • docker run -it --rm trinity1 dotnet run --no-build --project DistributedHashtable/DHT.GE.Client -- <docker-bridge-ip>:7000
