Graph Store

Description

Graph stores register through IFlexGraphStore, providing a provider-agnostic API for node/edge CRUD and traversals.

Configuration in DI

Register only the provider.

// Pick ONE
services.AddFlexNeo4jGraphStore(configuration);
// services.AddFlexCosmosGremlinGraphStore(configuration);

appsettings.json

Graph store configuration is read from FlexBase:DataStores:Graph:<Provider>.

{
	"FlexBase": {
		"DataStores": {
			"Graph": {
				"Neo4j": {
					"Uri": "bolt://localhost:7687",
					"Username": "neo4j",
					"Password": "<store-in-secrets>"
				}
			}
		}
	}
}

Sample usage ({YourApplication})

public class ConnectionFinder
{
	private readonly IFlexGraphStore _graphStore;

	public ConnectionFinder(IFlexGraphStore graphStore)
		=> _graphStore = graphStore;

	public Task<IReadOnlyList<FlexGraphNode>> FindPeopleAsync(CancellationToken ct = default)
		=> _graphStore.FindNodesAsync(label: "Person", limit: 50, ct: ct);
}

Provider pages

• Neo4j: graph-store/neo4j.md

• Cosmos Gremlin: graph-store/cosmos-gremlin.md

Provider considerations

• Graph providers vary in query language; prefer the structured IFlexGraphStore APIs for portability.
