qdrant-haystack 0.0.4

An integration of Qdrant ANN vector database backend with Haystack

qdrant-haystack

An integration of Qdrant vector database with Haystack by deepset.

The library finally allows using Qdrant as a document store, and provides an in-place replacement for any other vector embeddings store. Thus, you should expect any kind of application to be working smoothly just by changing the provider to QdrantDocumentStore.

Installation

qdrant-haystack might be installed as any other Python library, using pip or poetry:

pip install qdrant-haystack

poetry add qdrant-haystack

Usage

Once installed, you can already start using QdrantDocumentStore as any other store that supports embeddings.

from qdrant_haystack import QdrantDocumentStore

document_store = QdrantDocumentStore(
    url="localhost",
    index="Document",
    embedding_dim=512,
    recreate_index=True,
    hnsw_config={"m": 16, "ef_construct": 64}  # Optional
)

The list of parameters accepted by QdrantDocumentStore is complementary to those used in the official Python Qdrant client.

Connecting to Qdrant Cloud cluster

If you prefer not to manage your own Qdrant instance, Qdrant Cloud might be a better option.

from qdrant_haystack import QdrantDocumentStore

document_store = QdrantDocumentStore(
    url="https://YOUR-CLUSTER-URL.aws.cloud.qdrant.io",
    index="Document",
    api_key="<< YOUR QDRANT CLOUD API KEY >>",
    embedding_dim=512,
    recreate_index=True,
)

There is no difference in terms of functionality between local instances and cloud clusters.
