Cascading delete of instance

Hi @Erik Wiker!

As far I know Cognite CDF does not natively support cascading deletes for instances through both direct relations and edges. To achieve cascading deletes, you would typically need to implement custom logic within your application or python sciprt as follow.

 

from cognite.client import CogniteClient

def delete_instance_and_related(client, instance_id):
    # Find all relationships and edges related to the instance
    relationships = client.relationships.list(target=instance_id)
    edges = client.edges.list(target=instance_id)

    # Recursively delete related instances
    for relationship in relationships:
        delete_instance_and_related(client, relationship.source_id)

    for edge in edges:
        delete_instance_and_related(client, edge.source_id)

    # Delete the instance itself
    client.instances.delete(instance_id)

# Initialize the Cognite Client
client = CogniteClient()

# Call the function with the ID of the instance to delete
delete_instance_and_related(client, instance_id)
