FeatureStore

A FeatureStore object defines connection details for a data warehouse, as well as the location in the warehouse where partial aggregations (tiles) and feature tables are stored.

Registering a FeatureStore

To connect to your data warehouse, refer to the "Connecting to your Data Warehouse" section in the Get Started documentation. It summarizes the steps to connect to your:

Exploring the Feature Store's source tables

To explore the available source tables through the FeatureStore object, follow these steps:

  1. List the registered feature stores using the list() class method: 

    fb.FeatureStore.list()

  2. Retrieve the FeatureStore object by its name using the get() class method: 

    feature_store = fb.FeatureStore.get(<feature_store_name>)

  3. Obtain the DataSource object associated with the Feature Store object using the [get_data_source()](../../featurebyte.api.feature_store.FeatureStore.get_data_source method: 

    data_source = feature_store.get_data_source()

  4. Consult the DataSource and SourceTable documentation to learn how to explore each individual source table that the feature store can access.

Monitoring Deployments and Feature Job status

Once feature lists have been deployed and are being served, use the Deployment object class methods to list deployments across all catalogs:

  • list() to list all deployments across catalogs.
  • get() to get an Deployment object by its name.
  • get_by_id() to get a Deployment object by its Object ID.
fb.Deployment.list()

You can also get a report on the recent activity of scheduled feature jobs using the get_feature_jobs_status() method of a given deployment.

deployment = fb.Deployment.get_by_id(<deployment_Object_ID>)
deployment.get_feature_jobs_status(job_history_window=24)
