Research direction
Start by tracing the generated handler exception-mapping path described in the issue and inspect how AmazonServiceException reaches ProgressEvent.defaultFailureHandler. Determine how automatic throttling mapping should apply across generated resources, then verify that the repeated catch block is no longer required while CloudFormation retry behavior remains intact.
Written by the indexing model from the issue text.
Description
Cloudformation will do retry for retriable exception, such as throttling exception. However, it requires each handler to map the exception into CFN throttling error.
We should be able to auto map the exception to reduce the effort for all resource to map it. For example:
...................
} catch (AmazonServiceException ex) {
if (RetryUtils.isThrottlingException(ex)) {
logger.log(String.format("%s [%s] Create call throttled by downstream service", ResourceModel.TYPE_NAME, model.getAlarmName()));
return ProgressEvent.defaultFailureHandler(ex, HandlerErrorCode.Throttling);
}
