and can't therefore be used to trigger any backoff-and-retry logic within the lambda function itself. Instead, the exception thrown by the'ws close'event handler results in an unhandled exception that causes the
The runtime sends this message to Lambda to request an invocation event. The response body contains the payload from the invocation, which is a JSON document that contains event data from the function trigger. The response headers contain additional data about the invocation. ...

Using a synchronous (request response) call to the Lambda function can impact database performance, because the trigger has to wait for the function response to return. This post uses the asynchronous approach to optimize latency. For more information a...

Previously, you could get S3 bucket notification events (aka “S3 triggers”) when objects were created but not when they were deleted. With the new event type, you can now use Lambda to automatically apply cleanup code when an object goes away, or to help keep metadata or indices u...
