9 - Managing Coloring & Builds

📖 Task Introduction

Data Lineage allows you to manually color nodes on a graph to convey additional information, as well as to view build metadata attributes of datasets such as the time they were last built.

🔨 Task Instructions

1. In your Delays Permissions Graph, find and click the node named flight_alerts_preprocessed.
2. With flight_alerts_preprocessed selected, set up a custom color for this dataset by clicking on Color in the toolbar above the graph.
3. From the Color dropdown menu, choose any color.
4. Type the word “Preprocessed” under Color group name.
5. Click the checkmark to apply the color. This establishes the “Preprocessed” custom color group that will be shown in the legend in the top-right corner of the graph.
6. Click on the View node properties icon located along the right sidebar menu.

Within the node properties you can see the attributes of the selected dataset, such as when it was created, by whom, its job type (e.g., "Transform Python"), size (e.g., 267 MB) and more.

1. Click on Manage builds (the "hammer" icon) along the right sidebar menu.
2. With the default selection of Selected dataset(s) only, click on the blue Next (View preview) button. By reviewing the information in this sidebar, we can see that the flight_alerts_preprocessed table we selected is up-to-date and the Run build button is accordingly disabled. We won’t do this now as it would consume unnecessary resources, but note that the Force build on up-to-date datasets option would allow us to force a build.
3. Click Cancel to close this menu.
