Deletion Exceptions
Event bus deletion: To delete an event bus, you need to delete all its trigger rules and connectors first; otherwise, the error message "An event rule/connector has been bound to this event bus. Please try again after deleting the bound event rule" will be displayed. After the event bus is deleted from the data flow, all corresponding resource information will also be deleted.
Event rule deletion: To delete an event rule, you need to delete all its targets first; otherwise, the error message "An event target has been bound to this event rule. Please try again after deleting the bound event target" will be displayed. After the event rule is deleted from the data flow, delivery of events related to the rule to the corresponding event bus will also stop.
Event target deletion: The component resources of the relevant delivery logic will be deleted from the data flow.
Connector deletion: The connector resources will be deleted from the data flow, and messages will no longer be delivered to the corresponding event bus.
Retrial upon Exceptions
EventBridge retries when the delivery of an event to a downstream target fails.
