New welcome page

[betodealmeida]

The current welcome page — the page the user is redirected to when visiting the Superset root URL — is not functional, since it shows a list of dashboards for all users sorted by modification time. As Superset adoption grows inside a company, the welcome page becomes even less useful, with a reduced signal to noise.

At Lyft we discussed using a dashboard as the welcome page for our users, with a special configurable widget that displays tagged content. This requires some additions to Superset:

Tags

Saved queries, charts and dashboards would be able to be tagged by owners, using a react-tag-autocomplete. This would help with the organization of content, allowing users to create "virtual workspaces" (a feature that has been requested from our users), and would also be surfaced in a global search input.

These assets would also have "implicit" system tags, created and updated automatically. For example, a dashboard created by me (@betodealmeida) and favorited by @mistercrunch would have these system tags:

• type:dashboard
• owner:betodealmeida
• favorited_by:mistercrunch

Note that we use a colon as the separator. Regular, user-added, tags would be prohibited from having colons in their names.

Tagged object viewer (viz type or native dashboard)

A new dashboard widget would be created, either as a new visualization type or as a native dashboard component. This allows users to specify a list of tags, select object types (queries, charts, dashboards). Resulting matches would be shown in a table, with links:

Welcome dashboard

Admins would be able to create a dashboard, and have it as a template for new users — every new user would own a copy of that dashboard. This is useful for displaying company metrics, display welcome messages (using the Markup widget), and have a better onboarding experience.

This would be achieved by adding a variable to config.py, e.g., WELCOME_DASHBOARD_TEMPLATE, pointing to a dashboard id.

Custom welcome page

Currently users are redirected to http://example.com/superset/welcome when visiting the root URL for Superset. This would be configured in config.py, and in our deployment would point to the welcome dashboard.

Non-goals

Redesign user page

We all seemed to agree that the user page (http://example.com/superset/profile/$username/) is not very functional and could be improved. This is not part of this proposal.

Folks, I tried to split the functionality we want at Lyft into blocks that are useful by themselves, so we can build something useful but that's optional. Thoughts on each one of these items — tags, tagged object viewer, etc —?
