To preserve type information, Avro's json encoding tags union values with their type.
https://avro.apache.org/docs/current/spec.html#json_encoding If you wish to avoid this tagging, then you may use toString() on Avro data. This will generate valid Json, although some type information may be lost in the case of unions. For example, a union of a string and an enum cannot always be losslessly converted to and from Json without tagging. Nor can unions of ints and longs or unions of records and maps. Avro's type model is more complex than Json's. However if your schemas do not contain any unions that are ambiguous in Json then you can safely use toString().
