I think what you are looking for is the patternProperties field, rather than the properties one. Should look something like this, assuming you just want a match all pattern:

{
    "$schema": "http://json-schema.org/draft-04/schema",
    "title": "SomeSchema",
    "description": "SomeDescription",
    "type": "object",
    "properties": {
        "column_definitions": {
            "type": [
                "array",
                "null"
            ],
            "items": {
                "$ref": "#/definitions/columnDef"
            },
            "readOnly": true
        },
        "row_values": {
            "type": [
                "array",
                "null"
            ],
            "items": {
                "type": "object"
            },
            "readOnly": true
        }
    },
    "definitions": {
        "columnDef": {
            "type": "object",
            "patternProperties": {
                ".*": {
                    "type": "object",
                    "properties": {
                        "type": {
                            "type": [
                                "string",
                                "null"
                            ],
                            "enum": [
                                "Text",
                                "Boolean",
                                "Numeric",
                                "DateTime"
                            ],
                            "readOnly": true
                        },
                        "isNullable": {
                            "type": [
                                "boolean",
                                "null"
                            ],
                            "readOnly": true
                        }
                    }
                }
            }
        }
    }
}
