Thanks for reply.
Sadly it does not work that way (here). Even:
{
"name" : "ARecord",
"type" : "record",
"namespace" : "A",
"fields" : [
{"name": "id", "type": "string" },
{
"name": "B",
"type": {
"type": "record",
"name": "BRecord",
"fields": [
{
"name": "C",
"type": "string"
}
]
}
}
]
}
does not require C. And that's not what I want ... I'd like optional B, and
once user provide B, then B.C is required.
