Mythosia.AI.VectorDB

Package Summary

Provides InMemoryVectorStore, a thread-safe in-memory implementation of IVectorStore using cosine similarity search.
Suitable for development, testing, and small-scale workloads.

Usage

Automatically used as the default vector store in Mythosia.AI.Rag:

// Explicit selection (same as default)
.WithRag(rag => rag
    .AddDocument("docs.txt")
    .UseInMemoryStore()
)

Features

  • Thread-safe — Uses ConcurrentDictionary for safe concurrent access
  • Cosine similarity — TopK search with configurable result count
  • Namespace isolation — Filter by namespace for multi-tenant scenarios
  • Metadata filtering — Filter search results by key-value metadata
  • Minimum score — Discard results below a similarity threshold
  • Upsert — Single and batch upsert operations
  • Collection management — Create, check, and delete collections

Standalone Usage

using Mythosia.AI.VectorDB;

var store = new InMemoryVectorStore();

await store.CreateCollectionAsync("my-collection");

await store.UpsertAsync("my-collection", new VectorRecord
{
    Id = "doc-1",
    Content = "Some text content",
    Vector = new float[] { 0.1f, 0.2f, 0.3f },
    Metadata = { ["source"] = "manual.txt" }
});

var results = await store.SearchAsync("my-collection", queryVector, topK: 5);

Limitations

  • Data is not persisted — lost when the process exits
  • Not suitable for large-scale production workloads (millions of vectors)
  • For persistence or scale, implement a custom IVectorStore (e.g., Qdrant, Chroma, Pinecone)
