In general you don't need to wrap an unnamed complex type (map, array, union)
in a record.
Some language APIs might not support these 'naked' types with the same level of
ease that they support named ones.
Note in your schema below the "name" field -- "mapping" is completely ignored.
Maps don't have names.
Other 'nameless' schemas are ones with a single intrinsic data type, like:
{ "type": "int" }

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
