## Feast
|
|
|
|
[Feast (**Fe**ature **St**ore)](https://docs.feast.dev) is an open-source feature store that helps teams operate production ML systems at scale by allowing them to define, manage, validate, and serve features for production AI/ML.
|
|
|
|
Qdrant is available as a supported vectorstore in Feast to integrate in your workflows.
|
|
|
|
## Insatallation
|
|
|
|
To use the Qdrant online store, you need to install Feast with the `qdrant` extra.
|
|
|
|
```bash
|
|
pip install 'feast[qdrant]'
|
|
```
|
|
|
|
## Usage
|
|
|
|
An example config with Qdrant could look like:
|
|
|
|
```yaml
|
|
project: my_feature_repo
|
|
registry: data/registry.db
|
|
provider: local
|
|
online_store:
|
|
type: qdrant
|
|
host: xyz-example.eu-central.aws.cloud.qdrant.io
|
|
port: 6333
|
|
api_key: <your-own-key>
|
|
vector_len: 384
|
|
# Reference: https://qdrant.tech/documentation/concepts/vectors/#named-vectors
|
|
# vector_name: text-vec
|
|
write_batch_size: 100
|
|
```
|
|
|
|
You can refer to the Feast [documentation](https://docs.feast.dev/reference/alpha-vector-database#configuration-and-installation) for the full list of configuration options.
|
|
|
|
## Retrieving Documents
|
|
|
|
The Qdrant online store supports retrieving document vectors for a given list of entity keys. The document vectors are returned as a dictionary where the key is the entity key and the value being the vector.
|
|
|
|
```python
|
|
from feast import FeatureStore
|
|
|
|
feature_store = FeatureStore(repo_path="feature_store.yaml")
|
|
|
|
query_vector = [1.0, 2.0, 3.0, 4.0, 5.0]
|
|
top_k = 5
|
|
|
|
feature_values = feature_store.retrieve_online_documents(
|
|
feature="my_feature",
|
|
query=query_vector,
|
|
top_k=top_k
|
|
)
|
|
```
|
