>>> from teradataml import load_example_data, DataFrame, FeatureStore, FilterManager
>>> load_example_data('dataframe', 'admissions_train')
>>> df = DataFrame("admissions_train")

Create a FeatureStore.

>>> fs = FeatureStore(repo='vfs_v1', data_domain='sales')

Repo vfs_v1 does not exist. Run FeatureStore.setup() to create the repo and setup FeatureStore.

>>> fs.setup()

Create a FilterManager and load filter definitions.

>>> fm = FilterManager(repo='vfs_v1', name='stats_filter_manager')

Filter Manager 'stats_filter_manager' does not exist. Run FilterManager.load_filter() to create it.

>>> fm.load_filter(df=df.groupby('stats').count()[['stats']])
