does the map need to be embedded in a record

[Weishung Chung]

Hello,

I have a question about Avro schema. Does the map type need to be embedded
in a record? Could I have a schema like this without embedding the map in a
record?

{
    "name": "mapping",
    "type": "map",
    "values":{
        "type":"record",
        "name":"hi",
        "fields":[
            {"name":"a","type":"string"},
            {"name":"b","type":"string"}
        ]
    }
}


Thank you
