Event Rule

Resource Overview

An Event Rule represents an AWS EventBridge event rule. Event Rules allow you to configure your functions to be invoked when a message matching the rule is seen on the Event Bus. The triggering message is passed to the function as its input.

Key Features of EventBridge Event Rules include:

• Trigger functions in response to Event Bus events that match a pattern
• Create Event Rules that monitor the default Event Bus or a custom Event Bus
