Datasource Trigger Node

Use this node to start a workflow when a configured datasource emits a new event.

Configuration Fields

Field	Required	Purpose
Datasource	Yes	Select the datasource instance bound to this trigger
Filter Criteria	No	Optional criteria to allow only matching events

Setup Steps

1. Create datasource in project.
2. Add Datasource Trigger node.
3. Select datasource from list.
4. Optionally define filter criteria.
5. Connect to downstream validation node.

Best Practices

• Add schema/field validation right after trigger.
• Filter early to avoid unnecessary model inference.
• Keep one clear trigger path per workflow.

Common Issues

• No execution: datasource inactive/offline.
• Unexpected payload: source format changed.
• Excess load: missing filter criteria on high-volume streams.
