Static Graph / Connection

[navilan]

Hi,

I'm using Gremlinq in Azure FunctionApp. Would there be any problems in caching the graph object created from configure environment?

        public static IGremlinQuerySource MakeGraph(ILogger log) {
            if (_graph != null) return _graph; // static _graph
            _graph = GremlinQuerySource.g
                                          .ConfigureEnvironment(e => e.UseLogger(log))
                                          .ConfigureEnvironment(e => e
                                                                    .UseModel(GraphModel
                                                                             .FromBaseTypes<Vertex, Edge>(l =>
                                                                                  l.IncludeAssembliesOfBaseTypes())
                                                                             .ConfigureProperties(model =>
                                                                                  model.ConfigureElement<Vertex>(conf =>
                                                                                      conf.IgnoreOnUpdate(x => x.PartitionKey))))
                                                                    .UseCosmosDb(builder => builder
                                                                        .At(new Uri(ConnectionString), DbName, GraphName)
                                                                        .AuthenticateBy(PrimaryKey)));
            return _graph;
        }

Are there any recommended patterns to use Gremlinq in this manner?

Thanks so much,
Cheers,
Navilan

Caching is actually highly recommended. Preferrably, you'd register an IGremlinQuerySource via a dependency injection container (the one built into ASP.NET Core and Azure functions will already do) so you don't have to manage its lifetime by yourself.

Thank you, Daniel. Will follow through on the DI container. Been a while since I worked on the MS stack.
