Sylin.Koan.Data.Vector.Connector.Qdrant

Use Qdrant behind Koan's entity-first vector API. Referencing this package is the activation step; AddKoan() discovers it, elects it when appropriate, and reports the effective route at startup.

Maturity: Supported 0.20 extension within the capabilities and boundaries below.

Install and use

dotnet add package Sylin.Koan.Data.Vector.Connector.Qdrant
public sealed class Article : Entity<Article> { }

await Vector<Article>.Save(article.Id, embedding, new { category = "support" });
var matches = await Vector<Article>.Search(embedding, topK: 12);

No Qdrant-specific registration is required. With Qdrant reachable at http://localhost:6333, no configuration is required either. Set an endpoint only when the deployment differs:

{
  "Koan": {
    "Data": {
      "Qdrant": {
        "Endpoint": "https://cluster.example.qdrant.io",
        "ApiKey": "use-a-secret-provider"
      }
    }
  }
}

The first write establishes vector dimension. Set Koan:Data:Qdrant:Dimension only when the application must create an empty collection before any write. Koan defaults topK to 10; an explicit positive value is sent unchanged.

Honest capability boundary

Qdrant supports KNN search, metadata filters, bulk writes/deletes, embedding reads, collection clear, export through scroll, dynamic collection naming, and normalized cosine scores. This adapter does not claim hybrid text search, search continuation tokens, or index statistics.

Writes wait for visibility by default. Set WaitForResult to false only when ingestion throughput is more important than immediate read-after-write behavior. The default scalar-quantized, on-disk profile favors lower memory use; tune Quantization and OnDisk when recall and memory requirements differ.

Avoid pinning CollectionName in partitioned or tenant-isolated applications unless one shared collection is truly intended. A fixed name bypasses Koan's physical-name folds, and the runtime reports that correction.

See TECHNICAL.md for configuration, naming, health, and failure behavior.
