Alerts (send notification when a condition is met)

[benceorlai]

Motivation / Problem to Solve

Alerts provide the ability for the user to monitor a query and when pre-defined conditions are met, send a notification to a set of users. Notification can be via email, chat message or similar communication channel outside Superset. Alerts can be useful in the monitoring and alerting to anomalies, out of bound conditions, unexpected changes in business KPIs etc.

Superset's Alerts functionality was originally created as part of a hackathon at Preset. Ever since it has been demoed to companies, it has garnered a lot of interest. The feature was recently refactored substantially by Dropbox to make it more extensible in the future. Although the feature has garnered a lot of attention, it is still very early on in its lifecycle.

Proposed Solution

The scope of this project is to improve the usability and UX of Alerts:

• Deprecate the current FAB view based CRUD UI
• Build a new React based UI
• Apply UX/UI improvements to the user flow
