Looking at your examples, I can explain what these different event structures represent: 1. The first event shows a more complex relationship between multiple Prefect resources: - A flow run named "space-chihuahua" - A task run named "bigeye_integrity_checks_and_publish-ccd" that's part of that flow run - A flow definition named "build-prod" that this run is associated with This is a typical structure you'd see during flow execution, where you have the parent flow, a specific run of that flow, and task runs within it all linked together. 2. The second event is simpler, showing just a single webhook resource: - A webhook named "Upsert Catsy Products" - Note the different resource ID format (

prefect-cloud.webhook.*

instead of

prefect.*

) This simpler structure is typical for webhook events, which are standalone triggers that don't necessarily have the same parent-child relationships that flows and tasks do. The "related" array in these events helps establish the context and relationships between different Prefect resources. Each resource in the array has: - An ID (

prefect.resource.id

) - A role (

prefect.resource.role

) - A name (

prefect.resource.name

) This structure allows Prefect to maintain traceability and relationships between different components of your workflows, whether they're complex flow executions with multiple components or simple webhook triggers. Would you like me to dive deeper into any particular aspect of these event structures or how they're used in Prefect?
