What you'll be asked

  1. What is the primary purpose of a Feature Retrieval Specification in a production machine learning pipeline?
  2. When defining a retrieval specification, why is it critical to ensure that the feature join keys match exactly between the offline and online stores?
  3. Which component of a Feature Retrieval Specification is responsible for handling time-travel lookups during the creation of training datasets?
  4. In a production environment, what is the main risk of performing heavy feature transformations inside the retrieval specification rather than pre-computing them?
  5. If your retrieval specification fetches features from multiple sources, what mechanism should be implemented to ensure the model receives a unified feature vector despite different storage latencies?
