Data ingestion need to handle schema normalization
such as 
{
    "phones":
        {
            "425-000-0001": "private"
            "425-000-0002": "public",
            "425-000-0003": "public"
        }
}

need to convert to
{
    "phones":
        [
            {"key": "425-000-0001", "value": "private"},
            {"key": "425-000-0002", "value": "public"},
            {"key": "425-000-0003", "value": "public"}
        ]
}
