Should topologies with only topics be supported?

[purbon]

Currently it is possible to use a topology with only topics. While this might be of interest for setting up environments, it is clearly not a good practise for production like environments.

example topology:

---
team: "team"
source: "source"
projects:
  - name: "foo"
    topics:
      - name: "foo"
        config:
          replication.factor: "1"
          num.partitions: "1"
      - dataType: "avro"
        name: "bar"
        config:
          replication.factor: "1"
          num.partitions: "1"
  - name: "bar"
    topics:
      - dataType: "avro"
        name: "bar"
        config:
          replication.factor: "1"
          num.partitions: "1"

questions:

• should that even be supported?
• should this be supported, but raise a HUGE warning to notice the problem?

thoughts?

@kikulikov @jeanlouisboudart and others, thoughts?

imho this is a valuable feature - so if I would love to have this including the warning

but clearly is good for non-prod environments. End of the day we aim to set ACLs in prod, isn't?

This is possible as you can see from https://github.com/kafka-ops/kafka-topology-builder/blob/master/src/test/resources/descriptor-only-topics.yaml
