Hi,
I want to have a field in my schema which allows arbitrary Json data.
One option is to just encode the Json as a string:
{ "name": “ my_json_field”, "type": "string" }
But I'd rather encode the Json fields more efficiently. I saw that Avro
provides some kind of support for encoding arbitrary Json, via the schema
given here -
https://svn.apache.org/repos/asf/avro/trunk/share/schemas/org/apache/avro/data/Json.avsc
It would be nice if I could use this in my own schema, e.g. like this:
{ "name": “my_json_field”, "type": "org.apache.avro.data.Json” }
Has anyone done anything like this before?
Ultimately I want to be able to construct my Avro object in Java:
JsonNode node = /* Use Jackson mapper to parse JsonNode from String */
MyAvroType avro = MyAvroType.newBuilder().setMyJsonField(node).build();
Thanks for any advice on this,
Josh
