Hey! I want to use stream-maps to hash values in array, something like this

map(lambda x: md5(x['emailAddress']['address']), attendees)

I can’t do that after transfer, because I need anomized data in my DWH. Is it possible? Here’s my schema

"attendees": {
            "type": "array",
            "items": {
                "type": [
                    "object",
                    "null"
                ],
                "properties": {
                    "emailAddress": {
                        "type": [
                            "object"
                        ],
                        "properties": {
                            "address": {
                                "type": [
                                    "string",
                                    "null"
                                ]
                            },
                            "name": {
                                "type": [
                                    "string",
                                    "null"
                                ]
                            }
                        }
                    }
            }
        }
    }
