• ChatGPT provides a solution to achieve downstreaming patterns in applications by using the appropriate trigger, such as a database trigger, to invoke a Lambda function that parses the stream event and invokes the AppSync subscription.
• The Lambda function can use the AWS SDK and AppSync Client SDK to retrieve data from the database and trigger subscriptions from the backend to the front-end.
• However, the generated GraphQL schema and VTL resolver need to be adjusted to work with specific authorizations and data sources.
• While solutions from AI like ChatGPT can provide high-level guidance, Serverless architects are needed to implement the solutions accurately.
