ClickHouse.SemanticKernel

A Microsoft.Extensions.VectorData connector for ClickHouse, built on ClickHouse.Driver. Use ClickHouse as a vector store from Semantic Kernel and any other Microsoft.Extensions.VectorData consumer — CRUD, filtered queries, and vector similarity search through the standard SK interface.

Features

  • Vector similarity search via the native vector_similarity HNSW index with cosineDistance or L2Distance
  • LINQ-based filters translated to ClickHouse SQL (has(), hasAny(), null-safe equality, range predicates)
  • Upsert semantics on top of ReplacingMergeTree with FINAL reads for immediate consistency
  • Dynamic collections (Dictionary<string, object?>) alongside strongly-typed records
  • Client-side embedding generation via IEmbeddingGenerator<string, Embedding<float>>
  • DI integration via AddClickHouseVectorStore / AddClickHouseCollection

Usage

using ClickHouse.SemanticKernel;
using Microsoft.Extensions.VectorData;

public class Movie
{
    [VectorStoreKey] public string Key { get; set; } = "";
    [VectorStoreData] public string Title { get; set; } = "";
    [VectorStoreData(IsIndexed = true)] public int Year { get; set; }
    [VectorStoreData] public string[] Genres { get; set; } = [];

    [VectorStoreVector(Dimensions: 768, DistanceFunction = DistanceFunction.CosineDistance, IndexKind = IndexKind.Hnsw)]
    public ReadOnlyMemory<float> Embedding { get; set; }
}

var store = new ClickHouseVectorStore("Host=localhost;Protocol=http;Database=default");
var collection = store.GetCollection<string, Movie>("movies");
await collection.EnsureCollectionExistsAsync();

await collection.UpsertAsync(new Movie { /* ... */ });

var results = collection.SearchAsync(
    queryEmbedding,
    top: 5,
    new VectorSearchOptions<Movie>
    {
        Filter = m => m.Year >= 2015 && m.Genres.Contains("Sci-Fi")
    });

Requirements

  • .NET 8 runtime or newer (the package targets net8.0; building from source needs the .NET 10 SDK pinned in global.json)
  • ClickHouse 25.2+ (for the vector_similarity skip index)
