removalPolicy: RemovalPolicy.RETAIN

[skulljoi]

When I try to import the resource like Table I cant access some methodos like addGlobalSecondaryIndex because its part of Table and not TableBase, the same for S3 Bucket but with addEventNotification

Reproduction Steps

this.bucket = new Bucket(this, name, {
bucketName: 'name',
removalPolicy: RemovalPolicy.RETAIN
})
this.bucket.addEventNotification(EventType.OBJECT_CREATED, new SnsDestination(topic))

deploy and destroy this stack. Then you can try to redeploy without success because you already have the resource, then you change your stack to

this.bucket = Bucket.fromBucketName(this, id, 'name') as Bucket;
this.bucket.addEventNotification(EventType.OBJECT_CREATED, new SnsDestination(topic))

but method does not exists error

Error Log

TypeError: this.bucket.addEventNotification is not a function

Environment

• **CLI Version :aws-cli/2.0.3 Python/3.7.5 Windows/10 botocore/2.0.0dev7
• **Framework Version: cdk 1.38.0 (build d5fa31f)
• **OS :windows 10
• **Language :typescript

Other

I not sure if this is a bug, but this is the only way I had found in the cdk documentation to use an existent resouce.
If this is not a BUG how can I reuse the resource left by the removalPolicy: RemovalPolicy.RETAIN and reattach it to the stack?

The ability to adopt a resource into the stack is being tracked in aws/aws-cdk-rfcs#52

As you've gone through the exercise, you're right that existing resources that you're referencing using the fromXyZ methods which represent an object that can be used in your stack. In this case it's an IBucket. You can use methods to add grants and metrics on it.

The resource (table) itself is not governed by a stack (and therefore CDK).
