Qdrant — Vector Database Integration for DSPy

Guide the user through setting up Qdrant with DSPy using the official dspy-qdrant package, plus custom retriever patterns for Pinecone, ChromaDB, and Weaviate.

What is Qdrant

Qdrant is an open-source vector search engine written in Rust. It's the only vector database with an official DSPy integration package (dspy-qdrant). Features: hybrid search (dense + sparse), payload filtering, multi-tenancy, and horizontal scaling.

Why Qdrant for DSPy

DSPy 3.0 removed all community-contributed retriever modules (ChromadbRM, PineconeRM, WeaviateRM, QdrantRM from the main repo). The dspy-qdrant package is the official replacement — maintained separately with full DSPy compatibility.

For other vector databases, you write a short custom dspy.Retrieve subclass (~15 lines). This skill covers that pattern too.
