Domains

Last updated 14 days ago

What is a domain?

In Masthead, a domain represents a high-level category used to organize and manage related data products. Think of domains as logical groupings that often correspond to specific business areas, subject matters, teams, or strategic initiatives within your organization (for example "Finance", "Marketing", "Product Analytics", "Customer Support").

Purpose of domains:

  • Clearly assign responsibility for data products to a specific team or group.

  • Link domains to specific Slack channels for focused notifications, alerts, and discussions related to the data products within that domain.

  • Provide a rolled-up view of key metrics like cost and open incidents for all data products belonging to a domain.

Create Domain

You can easily define new domains to organize your data products.

1

Navigate to domains

Go to section in the menu, and click on the Domains tab. Click Create to open the "Create domain" side panel.

2

Fill in domain information

Provide a clear and unique Name for the domain (e.g., "Marketing Analytics", "Core Finance").

Enter the group Email address of the team responsible for overseeing the data products within this domain. This ensures clear accountability.

3

Assign Slack Channel

Select an existing Slack channel from the dropdown list if you want domain-specific notifications routed there.

To enable Slack integration: If the desired channel isn't listed:

  1. check that you've integrated your Slack Workspace in Integration settings.

  2. open the channel, type /invite @Masthead_data_app and hit Enter.

4

Click Create

Your newly created domain will now appear in the list.

Why use domains?

Domains provide significant value beyond simple categorization, particularly for teams responsible for producing, managing, and governing data.

Efficient communication & collaboration

Linking domains to specific Slack channels creates dedicated communication hubs. Data platform teams can route relevant alerts (e.g., pipeline failures affecting domain products) to the most relevant audience (the domain owners and key stakeholders), minimizing noise in broader channels. This helps reducing the total time spent analyzing the incidents.

Holistic Cost & Health Monitoring

Domains list view aggregates Monthly Cost and Open Incidents across all data products within each domain. This gives data teams and leadership a high-level overview of the operational burden and health status per business area, helping to prioritize resources for optimization or reliability improvements where they are most needed.

By implementing and utilizing domains in Masthead effectively, data teams can enhance accountability, streamline workflows, improve communication, gain better operational insights, and build a more organized and governable data ecosystem.
