Properties with `anyOf` indicator

[ewbankkit]

CloudFormation resource schema defined properties may include the anyOf indicator, for example AWS::DataBrew::Recipe:

    "Action": {
      "type": "object",
      "properties": {
        "Operation": {
          "description": "Step action operation",
          "type": "string"
        },
        "Parameters": {
          "anyOf": [
            {
              "$ref": "#/definitions/RecipeParameters"
            },
            {
              "$ref": "#/definitions/ParameterMap"
            }
          ]
        }
      },
      "additionalProperties": false,
      "required": ["Operation"]
    },

Currently our CloudFormation resource schema SDK ignores the anyOf indicator and when we come to generate a Terraform resource schema for the property it has no type.

It is not currently clear how to handle such properties.

Terraform as a language does not offer a way to model union types in the schema. This means we are currently unable to support attributes defined with the AnyOf qualifier.
