It seems to me that hassle of dynamic generation of one-off schemas
would make this bit sub-optimal use case.
Or, conversely, if you just define generic schema that allows sending
of key value pairs (and perhaps type), there is no size benefit as you
add all things that schema would help take out of payload.
Another alternative is to use content-type or related metadata to
allow use of different low-level data formats.
Beyond compressed JSON (which can be very fast with LZF or Snappy),
you could also consider one of binary encodings for Json.
