3 Introducing Metaflow

This chapter covers

Defining a workflow in Metaflow that accepts input data and produces useful outputs
Optimizing the performance of workflows with parallel computation on a single instance
Analyzing the results of workflows in notebooks
Developing a simple end-to-end application in Metaflow

You are probably anxious to roll up your sleeves and start hacking actual code, now that we have a development environment set up. In this chapter, you will learn the basics of developing data science applications using Metaflow, a framework that shows how different layers of the infrastructure stack can work together seamlessly.

The development environment, which we discussed in the previous chapter, determines how the data scientist ...

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.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
