While I can create custom objects just fine, I am wondering how one is supposed to handle large payloads (Gigabytes) for an object.

CRs are mostly used in order to interface with garbage collection/reference counting in Kubernetes.

Adding the payload via YAML does not work, though (out of memory for large payloads):

```
apiVersion: "data.foo.bar/v1" 
kind: Dump 
metadata:
  name: my-data
  ownerReferences:
    - apiVersion: apps/v1
      kind: Deploy
      name: my-deploy
      uid: d9607a69-f88f-11e7-a518-42010a800195
spec: 
  payload: dfewfawfjr345434hdg4rh4ut34gfgr_and_so_on_...

```

One could perhaps add the payload to a PV and just reference that path in the CR.
Then I have the problem, that it seems like I cannot clean up the payload file, should the CR get finalized (could not find any info about custom Finalizers).

Have no clear idea how to integrate such a concept into Kubernetes lifetimes.
