Panther schemas: does the "required" flag propagate to subfields as well?

QUESTION

If I have a required field in my schema that's of type object, will the subfields of the object be required by default too?

ANSWER

No, if you have an object field, the subfields are all optional by default, regardless of whether the object field is required or not. For a subfield to be required, you need to explicitly mark it as such. In the example below, myObj.foo is an optional field, but myObj.bar is required.

fields:
  - name: myObj
    type: object
    required: true
    fields:
        - name: foo
          type: string
        - name: bar
          type: bigint
          required: true
