Hopsworks API key

In order for the Databricks cluster to be able to communicate with Hopsworks, clients running on Databricks need to be able to access a Hopsworks API key.

Generate an API key

For instructions on how to generate an API key follow this user guide. For the Databricks integration to work make sure you add the following scopes to your API key:

  1. featurestore
  2. project
  3. job
  4. kafka

Quickstart API key Argument

!!! hint "API key as Argument" To get started quickly, without saving the Hopsworks API in a secret storage, you can simply supply it as an argument when instantiating a connection:

    import hopsworks 
    project = hopsworks.login(
        host='my_instance',                 # DNS of your Feature Store instance
        port=443,                           # Port to reach your Hopsworks instance, defaults to 443
        project='my_project',               # Name of your Hopsworks Feature Store project
        api_key_value='apikey',             # The API key to authenticate with Hopsworks
    )
    fs = project.get_feature_store()           # Get the project's default feature store

Next Steps

Continue with the configuration guide to finalize the configuration of the Databricks Cluster to communicate with the Hopsworks Feature Store.
