Chapter 3: Feature Store Fundamentals, Terminology, and Usage

In the last chapter, we discussed the need to bring features into production and different ways of doing so, along with a look at common issues with these approaches and how feature stores can solve them. We have built up a lot of expectations about feature stores, and it's time to understand how they work. As mentioned in the last chapter, a feature store is different from a traditional database – it is a data storage service for managing machine learning features, a hybrid system that can be used for storage and retrieval of historical features for model training. It can also serve the latest features at low latency for real-time prediction, and at sub-second latency for batch ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.
