Episode 8: Autopilot

Scheduling Compute in the Cloud.​

This example revisits 'Episode 06-statistics-redux: Computing in the Cloud'. With Metaflow, you don't need to make any code changes to schedule your flow in the cloud. In this example, we will schedule the stats.py workflow using the step-functions create command-line argument. This instructs Metaflow to schedule your flow on AWS Step Functions without changing any code. You can execute your flow on AWS Step Functions by using the step-functions trigger command-line argument. You can use a notebook to set up a simple dashboard to monitor all of your Metaflow flows.

You can find the tutorial code on GitHub.

Showcasing:

  • step-functions create command-line option
  • step-functions trigger command-line option
  • Accessing data locally or remotely through the Metaflow Client API
