Versioning features in a feature store is not necessary as it does not provide any significant benefits and can be avoided.

Versioning features in a feature store is important to maintain consistency, track changes, and improve the reproducibility of machine learning models. To version features in Databricks, first, create a new version of the feature store table. Then, write the new version of the features to the table using the feature store API. Finally, update the model training and scoring processes to use the new version of the features.

Versioning features in a feature store is a manual process that requires custom code for each step.

To version features in Databricks, simply create a copy of the feature store table and modify the copied table as needed.
