Lambda triggers
If you are looking to enable triggers for the Storage Category with Amazon S3 & Amazon DynamoDB as Providers, the CLI supports associating Lambda triggers with S3 and DynamoDB events. For example, this can be useful for a use case where you want to invoke a Lambda function after a create or update operation on a DynamoDB table managed by the Amplify CLI.
For more information on this topic, please read on File Storage Lambda Triggers through our Amplify CLI documentation.
