Tessera.KernelMemory

Kernel Memory connector for Tessera vector database - enables RAG and semantic memory with Tessera backend.

Features

  • Full IMemoryDb implementation for Microsoft Kernel Memory
  • Semantic search with text embedding
  • Tag-based filtering
  • Payload storage and retrieval
  • Multi-tenant support via index mapping

Installation

dotnet add package Tessera.KernelMemory

Quick Start

using Microsoft.KernelMemory;
using Tessera.Client;
using Tessera.KernelMemory;

// Create Tessera client
var tesseraOptions = new TesseraClientOptions
{
    Endpoint = "https://your-tessera-instance:50051"
};
var tesseraClient = new TesseraClient(tesseraOptions);

// Create config
var config = new TesseraMemoryDbConfig();

// Create embedding generator (use your preferred provider)
ITextEmbeddingGenerator embeddingGenerator = /* your embedding generator */;

// Create memory database
var memoryDb = new TesseraMemoryDb(tesseraClient, config, embeddingGenerator);

// Create an index
await memoryDb.CreateIndexAsync("my-documents", vectorSize: 384);

// Upsert a memory record
var record = new MemoryRecord
{
    Id = "doc-1",
    Vector = embedding,
    Tags = new TagCollection { { "type", "document" } },
    Payload = new Dictionary<string, object> { { "title", "My Document" } }
};
var id = await memoryDb.UpsertAsync("my-documents", record);

// Search for similar content
await foreach (var (result, relevance) in memoryDb.GetSimilarListAsync(
    "my-documents",
    "search query text",
    limit: 10,
    minRelevance: 0.7))
{
    Console.WriteLine($"Found: {result.Id} (relevance: {relevance:P})");
}

Supported Operations

Method Status
CreateIndexAsync Supported
GetIndexesAsync Supported
DeleteIndexAsync Not supported (Tessera limitation)
UpsertAsync Supported
GetSimilarListAsync Supported
GetListAsync Supported (workaround)
DeleteAsync Supported

Known Limitations

  • DeleteIndexAsync throws NotSupportedException - Tessera backend doesn't support tenant deletion
  • GetListAsync uses a dummy vector search as workaround (Tessera lacks "list all" RPC)
  • Only single metadata filter supported per search (Tessera proto limitation)

Requirements

  • .NET 9.0 or later
  • Tessera vector database instance
  • Microsoft.KernelMemory.Core 0.98+
