The Database Trigger step is your workflow’s starting point. Use this step to define which changes in your database (or external events) will automatically kick off your workflow.
To add this trigger, ask the AI Agent for the workflow you want. It will automatically create the trigger for you based on your database schema and your workflow goals. For any changes you’d like to make, you can either ask the AI or adjust the schedule details manually in the editor.
Database Trigger Example

​
Breakdown

Pick a schema & table

Choose the schema and table to watch. Dreamlit automatically infers the output shape of the data from the table structure.

Select trigger type

Decide whether the trigger should fire on new rows (insertions), updates, or both. For updates, you can optionally specify the columns to watch.
Note: the trigger only becomes active and applied to your table when you publish your workflow. Until then, no events will be logged.
