You can use Record or any other type supported by avro as the value type of
Map,here is an example:
{
"name": "mapping",
"type": "map",
"values":{
"type":"record",
"name":"hi",
"fields":[
{"name":"a","type":"string"},
{"name":"b","type":"string"}
]
}
}
Also,you can use nested schma in record fileds.
