The Qdrant Output Connector

The Qdrant Output Connector integrates Qdrant, a Rust-based vector database, into OpenCrawling's enterprise RAG system to enable high-performance similarity search with built-in security controls through payload-based ACL filtering. The connector automatically provisions Qdrant collections with security indexes and uses a decoupled microservice architecture—combining document ingestion, text extraction, embedding generation, and high-speed gRPC-based vector storage—to ensure users only retrieve documents they have authorization to access. The system is fully configurable via Spring Boot properties and supports self-hosted or cloud-based Qdrant deployments.
