## Decision facts: qdrant

- **Hosting:** self hosted - Qdrant supports self-hosted deployment along with a cloud option at https://cloud.qdrant.io/.
- **Requirements:** - Distributed deployment with sharding and replication is supported.; - No specific minimum RAM requirement provided. Performance and resource use will depend on the scale of embedding collections.
- **Adopt for:** High-performance vector database with support for distributed deployment.
- **License detail:** Qdrant is available under the Apache License 2.0.

## Choose when

### Choose NumKong if…

- NumKong is primarily C; qdrant is Rust.
- Tags unique to NumKong: matrix-multiplication, assembly, blas, cpp.
- Also covers Evaluation & Observability.

### Choose qdrant if…

- qdrant is primarily Rust; NumKong is C.
- Qdrant supports self-hosted deployment along with a cloud option at https://cloud.qdrant.io/.
- Requirements: - Distributed deployment with sharding and replication is supported.; - No specific minimum RAM requirement provided. Performance and resource use will depend on the scale of embedding collections..
- Tags unique to qdrant: knn-algorithm, vector-search-engine, vector-database, embeddings-similarity.
- - When scalability and performance are paramount in handling large-scale embeddings.

## When NOT to use NumKong

- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.

## When NOT to use qdrant

- - Avoid if your project requires more traditional relational database features as Qdrant focuses exclusively on vectors.
- - If minimalistic setup is crucial, since Qdrant's capability for distributed deployment may introduce complexity that is not necessary for smaller-scale applications.
- - For use cases where non-Rust environments significantly limit the feasibility of integrating external tools.
