Sylin.Koan.Data.Vector.Connector.SqliteVec

Durable, exact vector search in one local SQLite file, with no vector server or provider ceremony.

  • Target framework: net10.0
  • Native engine: sqlite-vec v0.1.9
  • License: Apache-2.0

Smallest meaningful result

builder.Services.AddKoan(koan =>
    koan.Data.Source("Semantic").Vector<Article>(space => space
        .Name("articles")
        .Dimensions(1536)
        .Metric(VectorMetric.Cosine)
        .Visibility(VectorVisibility.Session)));

await Vector<Article>.Save(article.Id, embedding, new { article.Category }, ct);

var nearest = await Vector<Article>.Search(
    embedding,
    query => query.Top(12).AtLeast(.82),
    ct);

The package discovers itself through AddKoan. By default it pairs with the selected SQLite record source; configure Koan:Data:Sources:<name>:SqliteVec:ConnectionString when vectors belong in a separate file.

Guarantees

  • exact native cosine or Euclidean kNN with finite [0,1] similarity and stable identity ties;
  • atomic complete-point upsert and atomic ordered batches;
  • immediate Session visibility and file-backed restart durability;
  • positional get-many, truthful delete outcomes, and lossless neutral metadata;
  • source, partition, and Koan hard-scope isolation;
  • ReadOnly and External policy enforcement before file or shape mutation;
  • pinned native RID payloads verified by SHA-256 and vec_version() before use.

SqliteVec deliberately declines dot product, arbitrary metadata Where(...), hybrid search, Eventual visibility, continuations, streaming export, and multiple vectors per Entity. Unsupported intent fails with a corrective exception; the adapter never substitutes a managed scan or a weaker result.

Supported native platforms

  • Windows x64
  • Linux x64
  • Linux arm64

An unsupported RID fails before a database operation. Native library paths and extension-loading controls are not application configuration.

Bounded options

Koan:Data:SqliteVec:MaxMetadataBytesPerPoint and MaxSearchCandidates bound per-point metadata and stable-tie expansion. Dimensions, metric, visibility, placement policy, and space name remain shared Koan decisions.
