Zoltan Farkas commented on AVRO-1582:
-------------------------------------
I have pushed out a implementation of the Json encoders/decoders that improve
the following:
1) union {null, type} is serialized/deserialized naturally to JSON.
2) Fields equal with the default value are omitted at serialization time, and
inferred from writer schema at deserialization time. (this makes the json
messages significantly more compact in certain use cases)
for more detail see:
https://github.com/zolyfarkas/avro/commit/8926d6e9384eb3e7d95f05a9d1653ba9348f1966
I would be interested in some feedback, and some help integrating this if there
is interest.
cheers
