(lambda): Unnecessary custom resource for Lambda log retention?

See original GitHub issue

❓ General Issue

Custom CloudFormation resource is created to set Lambda Log Retention

When added logRetention to a Lambda, a custom resource is created.

        return Function.Builder.create(this, id)
                .code(Code.fromAsset("qrcode-service-lambdas/qrcode-processor/target/qrcode-processor.zip"))
                .handler("io.quarkus.amazon.lambda.runtime.QuarkusStreamHandler::handleRequest")
                .runtime(Runtime.JAVA_11)
                .logRetention(RetentionDays.ONE_WEEK)
                .build();

It looks like this is a workaround for a lerna issue in CDK itself? https://github.com/aws/aws-cdk/blob/3727c715e17b5fb41a8a7a6f012d5a1936bac347/packages/%40aws-cdk/aws-logs/lib/log-retention.ts#L82-L82

Shouldn’t there be a better way/workaround instead of creating unnecessary resources like this in AWS? It’s very confusing to explain to people who are less familiar in AWS why this is needed. With AWS SAM/Serverless Framework this is not required.

Even with the core L2 construct it still would be a custom resource?

Yes because a log group is created implicitly when a Lambda function starts to log. So we need a custom resource to cover all the edge cases as discussed in #248 and #667.
