Method AddVectorStore

Namespace

Qavren.Edge.VectorData

Assembly

Qavren.Edge.VectorData.dll

AddVectorStore(EdgeBuilder, Action<EdgeVectorStoreOptions>?)

Registers EdgeVectorStore and MEVD's VectorStore over the named sub-project 1 database, plus the diagnostics contributor and the lifecycle observer.

Embedding generator resolution, which is what makes the four-call path work. The registered factory resolves IEmbeddingGenerator from the container with GetService - never GetRequiredService, because a store used only with pre-computed ReadOnlyMemory<T> vectors needs no generator and demanding one would break that. The result goes to EdgeVectorStore's embeddingGenerator parameter, which applies it only where EmbeddingGenerator is still null.

The query generator is then resolved from the generator itself, by service key, with no reference to Qavren.Edge.Embeddings.Onnx: the key is this package's own QueryGeneratorServiceKey, the call is GetService rather than the ONNX package's AsQueryGenerator() convenience, and it asks for the non-generic IEmbeddingGenerator - a third-party generator may be typed IEmbeddingGenerator<DataContent, Embedding<float>>, and asking for a closed generic it does not implement would return null and quietly lose the query lane.

Builder-call order does not matter, because the factory runs at resolve time.

public static EdgeBuilder AddVectorStore(this EdgeBuilder builder, Action<EdgeVectorStoreOptions>? configure = null)

Parameters

builder EdgeBuilder

The Qavren.Edge builder.

configure Action<EdgeVectorStoreOptions>

Configures the store options.

Returns

EdgeBuilder

The builder, for chaining.

AddVectorStore(EdgeBuilder, string, Action<EdgeVectorStoreOptions>?)

Keyed variant. Resolves the keyed IEmbeddingGenerator under the same name first, then the unkeyed one, so a named store pairs with a named generator by convention.

public static EdgeBuilder AddVectorStore(this EdgeBuilder builder, string name, Action<EdgeVectorStoreOptions>? configure = null)

Parameters

builder EdgeBuilder

The Qavren.Edge builder.

name string

The service key the store registers under.

configure Action<EdgeVectorStoreOptions>

Configures the store options.

Returns

EdgeBuilder

The builder, for chaining.
