DataSource

A DataSource object represents a collection of source tables that the feature store can access.

This object is obtained from the FeatureStore object it is linked to using the get_data_source() method:

feature_store = fb.FeatureStore.get("playground")
data_source = feature_store.get_data_source()

Follow below steps to access the source tables available in the data source:

1. Retrieve the list of databases in the data source using the list_databases() method:

   ds.list_databases()
   

2. Obtain the list of schemas within the desired database using the list_schemas() method:

   ds.list_schemas(database_name='spark_catalog')
   

3. Access the list of tables contained in the selected schema using the list_source_tables() method:

   ds.list_source_tables(database_name='spark_catalog', schema_name='grocery')
   

4. Obtain a SourceTable object using the get_source_table() method:

   source_table = ds.get_source_table(
       database_name="spark_catalog",
       schema_name="GROCERY",
       table_name="GROCERYCUSTOMER"
   )
