You can use apply() to modify an existing component:
  1. Get the corresponding component.
  2. Modify the corresponding component's property.
  3. Pass the same component again to apply().

Usage

  • Do not not modify name of any component. If you modify name and push it to FeatureStore, a new component will get created with that name.
  • You can modify multiple properties of a component and add it back to FeatureStore once all the modifications are done.
  • If you get a FeatureGroup, you can modify the underlying Features, Entity, or DataSource. If you push FeatureGroup after modification, then underlying Features, Entity, or DataSource will also get modified.

Example: Modify a Feature

Get the feature 'sales_mar' from repo 'vfs_v1', modify the description, and update it to FeatureStore.

>>> feature = fs.get_feature('sales_mar')
>>> feature.description
'Feature of sales.'
>>>
>>> feature.description = 'Feature for March sales.'
>>> fs.apply(feature)
True
>>> fs.get_feature('sales_mar').description
'Feature for March sales.'

Example: Modify a FeatureGroup and underlying DataSource

Get the FeatureGroup with group name 'sales' from repo 'vfs_v1'.

>>> fg = fs.get_feature_group('sales')

Update the FeatureGroup description.

>>> fg.description = 'Sales Group'

Update the associated DataSource description.

>>> fg.data_source.description = 'sales data source.'

Update the details to repo.

>>> fs.apply(fg)
True

Verify the updated details.

>>> fg = fs.get_feature_group('sales')
>>> fg.description
'Sales Group'
>>> fg.data_source.description
'sales data source.'
