What is the Qdrant Python client's QdrantClient, and how does it abstract REST and gRPC?

QdrantClient is the official Python client used to interact with Qdrant without manually constructing every API request. It exposes Python methods for collections, point operations, search, filtering, and other Qdrant features.

The client can communicate using REST or gRPC, allowing application code to work with a consistent Python API while the transport is selected through client configuration. That abstraction is useful because changing transport does not require rewriting every application operation.

The trade-off is that an SDK adds another abstraction layer. For unusual features, newly released APIs, or debugging protocol-specific behavior, I may inspect the generated request or use the underlying HTTP/gRPC interface directly. Client and server versions should also be checked for compatibility.

A common mistake is assuming the Python client itself performs vector search. The search engine runs in Qdrant; the client primarily handles request construction, transport, serialization, and response mapping.
