About Qdrant
An open-source vector database in Rust, built for high-recall similarity search at scale.
Qdrant is a vector similarity search engine and database written in Rust, released under the Apache 2.0 licence. Andrey Vasnetsov and Andre Zayarni founded the company in Berlin in 2021 after Andrey built a production-grade vector engine from scratch and put it on GitHub. The team now ships the open-source database alongside Qdrant Cloud on AWS, GCP and Azure, a Hybrid Cloud option that runs the data plane in your own Kubernetes, and a Private Cloud variant for air-gapped deployments.
The data model is straightforward: a collection holds points, and each point carries one or more dense vectors, optional sparse vectors, and a JSON payload with the metadata you want to filter on. The HNSW index handles approximate nearest-neighbour search, payload indexing makes filters cheap, and quantisation cuts RAM use for large collections. REST and gRPC are both first-class, with official clients in Python, JS/TS, Go, Rust, Java and .NET.
For a Data Panda customer the role is clear: Qdrant is the vector layer, not the system of record. The warehouse is where the source documents, tickets, products and knowledge base live; Qdrant is where the embedded representation lives so an assistant or a search box can find the relevant slice in milliseconds. Pulling collection state back into the warehouse is what makes the loop measurable, because hit-rate, drift and query quality only show up when the vector side and the source side sit in the same model.
