Feature Store for Machine Learning

By: Jayanth Kumar M J

Overview of this book

Feature store is one of the storage layers in machine learning (ML) operations, where data scientists and ML engineers can store transformed and curated features for ML models. This makes them available for model training, inference (batch and online), and reuse in other ML pipelines. Knowing how to utilize feature stores to their fullest potential can save you a lot of time and effort, and this book will teach you everything you need to know to get started. Feature Store for Machine Learning is for data scientists who want to learn how to use feature stores to share and reuse each other's work and expertise. You’ll be able to implement practices that help in eliminating reprocessing of data, providing model-reproducible capabilities, and reducing duplication of work, thus improving the time to production of the ML model. While this ML book offers some theoretical groundwork for developers who are just getting to grips with feature stores, there's plenty of practical know-how for those ready to put their knowledge to work. With a hands-on approach to implementation and associated methodologies, you'll get up and running in no time. By the end of this book, you’ll have understood why feature stores are essential and how to use them in your ML projects, both on your local system and on the cloud.

Creating Feast resources in AWS

As discussed in the previous chapter, Feast aims to provide a quick setup for beginners to try it out; however, for team collaboration and to run a model in production, it requires a better setup. In this section, we will set up a Feast environment in the AWS cloud and use it in model development. In the previous chapter, we also discussed that Feast provides multiple choices when picking an online and offline store. For this exercise, Amazon S3 with Redshift will be used as an offline/historical store and DynamoDB will be used as an online store. So, we need a few resources on AWS before we can start using the feature store in our project. Let's create the resources one after another.

Amazon S3 for storing data

As mentioned in the AWS documentation, Amazon Simple Storage Service (Amazon S3) is an object storage service offering industry-leading scalability, data availability, security, and performance. Feast provides the capability to use...
