How to Build Machine Learning Systems With a Feature Store

The MLOps Blog

A feature store typically comprises a feature repository, a feature serving layer, and a metadata store. It can also transform incoming data on the fly. The metadata store manages the metadata associated with each feature, such as its origin and transformations. All of them are written in Python.
